Premio X86 Ackerman's ***

Good day I bought a phone 2 years ago a Premio X86 and last year around June\July the phone had issues with the speaker and slowness of the software they done a replacement of the whole phone now the phone is falling apart on its own and its even switching off i went to one of Ackerman's shop (Southgate) and was told the phone is out of warranty yet when they done a phone swop i wasn't told that warranty is being continued on my side new phone new warranty it’s not even a year the phone is already falling apart what quality is that phone and how come i have the same issues phone speaker and slowness the new one on this phone its switching off on its own, also how come it wasn’t explained that the warranty is continuing on the old phone i wouldn’t have waisted my time taking a day off work coming to the shop to be told no they can’t help, also the biggest fall out of the phone it switched off during the interview I couldn’t join the session as the phone kept looping also during normal calls some days the phone would remain blank yet the is an incoming call and people think im avoiding them yet it’s the phone brand im honestly tired of going back and forth, also the is someone closing the call by the name of *** Phathiswa Gumenge please advise if possible is the away forward except burning the device..
