A gang of thieves !!! Here is how the service is going at home: the 10/03/2019 I buy my phone (a BV9600Pro) on the site teknistore.com the 26/03/2019 I received it But no bowl he is failing (compass) the 28/03/2019 I made my request for rma. I followed the procedure requested by the Teknistore RMA service asking me, photos, videos, re-initialization, ... the 11/04/2019 the taking in guarantee was finally accepted. the 03/05/2019 so I sent at my expense the phone (time to find a replacement phone). on 13/05/2019 the package arrived at the destination concerned. the 04/06/2019, services teknistore informs me that the care takes up to 45 days. Delays that I find abnormally long for a default of origin. Following several emails, the 02/07/2019 I am told that the problem is about to be solved and that an answer will be given to me within 24 / 48h. the 15/07/2019 I am threatened not to take into account my guarantee following a negative opinion left on the current site, out of desperation. I withdraw this notice immediately following this threat. on 17/07/2019 I am told that I will be given a tracking number. the 22/07/2019, the service always seems to wait for the tracking number. The 28/07/2019, the package is deposited at the office of departure, we will soon give me a tracking number ... But now that I'm starting to believe it a little ... the 06/08/2019, I am told that it is necessary to replace the motherboard (while it is supposed to be already sent !!!) the 15/08/2019 I'm finally given a tracking number. And there, attention, hang well ... The 29/08/2019 I receive the package with ... A BV9500 instead of a BV9600. Following all these misadventures I did not agree to dismiss the latter because I am extremely disappointed in the quality of the distributor "Tecknistore" and I do not think they would ever be able to send me back my phone. In short I used my phone 1-2 weeks without ever reviewing the color since 03/05/19 So pay attention to this site and especially to its after sales service. They are not serious and threaten you.
