I never go out of my way to leave complaints or negative comments, however, what I experienced the other was absolutely horrendous on many terms. I bought an iPad Pro from the two days ago from the Deira City Center branch and returned to buy a screen protector. I asked the lady behind the counter at the screen protector department to show me what they have for the 10.5 screen. She had no knowledge about the products and showed no interest in explaining, either. She showed me one type of glass protector until I asked her about the other one (on display). I asked her to kindly install the screen for me, in which she did the following: She placed the iPad directly on the display glass without checking to see if there was anything that could potentially scratch the device. Bear in mind that I actually brought the device in the box, so it had no back cover. Any other store actually use a rubber mat to place devices on or just any soft sheet. The lady then starts to apply it without making sure that the screen was absolutely clean, so as to avoid any dust entrapped under the glass. She struggled with applying it and took about 15 minutes. After I inspected the screen protector, I noticed many dust particles (clear ones) under the glass screen, as well as two very obvious scratches. If staff members aren't informed about this: you are not supposed to use glass cleaning products or alcohol swabs on the glass protector because it rips off the top layer and causes it to be weaker. She proceeds to spray so much of the glass cleaning product in hopes of the dust particles to magically disappear. After I pointed out the obvious dust particles, she took the iPad and starts using a HAIR DRYER on the iPad directly. I kindly asked her to stop doing that, as the screen protector I was purchasing was flexi glass and is made of very thin material which will damage the iPad screen for sure if I hadn't stopped her. She mockingly said: "we are trained professionals". I said: "yes, but it's not right to use a hair dryer on a sensitive screen like an iPad's. I could've done this myself in a steamed room", to which she replied: "haha, the steam will damage the screen". Clearly, she had not tried it herself to know that water has better effect on an adhesive screen than hot, dry air which could damage the Sapphire Glass on the iPad! If I have good knowledge about in my life, it's what to do and what no to do to electronic devices and I am well aware of the information I attain. She clearly lacks a good understanding of what she should be doing and selling in her position at Sharaf DG and also speaks to customers in a rude way, whether they are right or wrong. She seems completely incompetent and incapable of working in a technical store where information like that is crucial to have. When the customer has more knowledge than the "trained" staff members, know that the store will be in jeopardy. She scoffs: "well, if you're not happy I'll just remove it." She proceeds to call her superior, who in turn said: "ma'am we can't help it, if you're not happy, we will just remove it." Out of concern and respect for the employees I said that I would ask for a discount so that in that case they wouldn't lose money over the product, and that I could discuss it with the manager. The man literally said: "Ma'am I am the manager in Screen Protection department, we cannot do that". I said: "it has dust particles and scratches on it." He replied with: "but it's normal!" I agreed to remove the screen protector, which then the lady proceeds to rip off aggressively and mockingly. I said thank you and left. I do not want to have to deal with this again at Sharaf DG, as it isn't the first time! Mind you, I had gone to another store right after that trauma and had a great customer experience with that shop (I will keep their identity a secret as to not seem like I am trying to compare). The staff knew what they were doing and dealt with the iPad very gently and told me that I shouldn't be using the alcohol swab on the glass protector to not damage it. They understood completely what I was concerned about and claimed all responsibility. Guess what? No dust particles or scratches.
