FNB does not respond to problems/complaints!

<p>I took out a contract for an iPhone5 with FNB which I received at the beginning of November 2016. About two weeks later I allowed the battery to go completely flat. After that it would not recharge. FNB requested me to take it to the nearest iStore which is contracted to do their repairs. I received a quote from the iStore that I need to pay R5 000+ for a replacement phone as the phone is no longer under warranty. And that is when my problems started. After almost daily phone calls to FNB Technical Services (the calls cost approximately R10 each time) and every excuse under the sun, I wrote a complaint on their webpage. The webpage promised a response within 24 to 48 hours. Well, it is now about two weeks later and I have yet to receive a response. Their Technical Services agents always promise to" look into what is going on and I will phone you back". Not one agent has ever phoned me back. It is now more than 2 months later and I am still without a cellphone, but my monthly deductions are going off my bank account. What do I do?</p>
