Samsung needs staff that know what they doing!!!

STAFF NOT COMPETENT IN THEIR WORK!! Samsung at the Wedge Shopping Centre has the most terrible service!!! My Samsung A7 phone's Bluetooth was not working correctly. It was taken to the store for fixing. Sent me an email and called to say the phone was fixed and ready for collection. I got there only to find it was not. waited 20 minutes and then took the phone home only to find its still not working. took it back to the store and sat there for an hour and 40 minutes waiting for them to fix it. now after 2 technicians looking at the phone, they still cannot find what is wrong. they wiped out my phone and now the new software is not compatible with me fitbit device. who's fault is this??? Tarique says its not the Samsung device problem.. then what is???? everything was working fine up until these people wiped my phone out! 4 trips to the store but no results what so ever!! they just expect you to keep going up and down.

PATHETIC SERVICE AND THEY DO NOT KNOW WHAT THEY DOING
