FNB Connect pathetic after service

Whatever you do please DO NOT buy a Conexis A2 from any FNB bank. My battery just went dead and i logged a complaint to tell them I need a battery. I have logged numerous complaints with FNB sending me a mail telling me to call a company that sells batteries for this kind of phone. I have called that place and mailed them and still no response. FNB mailed me to tell me they have asked them to call me i am still waiting for this place to call me, mail etc. Yet every damn month they deduct the R69 for the device but their after service is pathetic to say the least. Im about to loose my **** real soon and Im tired of asking the same thing over and over again. So whatever you do DO NOT BUY A PHONE OR ANY DEVICE FROM FNB!!!ive tried installing the fnb app on my sons phone i cant even do log in on that app. Then it asks for my approval on my fnb sim card that i cannot even use in another phone cause the sim is blocked until account is paid then they give you an unlock pin. i cannot even on my online banking change the cell number cause it asks for approval from my fnb sim that i CANNOT USE!!!my blackberry i was using's battery also broke so now my vodacom sim doesnt fit in any phone so they cant even phone me how awesome. only mail. way to go FNB Connect after service!!!!
