Pathetic service once again

This is the 2nd device that I purchased from FNB and am truly disappointed. My initial phone purchased from FNB was returned as it could not be repaired - this is after sending it back more than 2 times and having had numerous problems. The second device/phone is problematic and its not even three months that I have it. We've contacted FNB and were now told that we need to take the phone in to the branch in Benoni in order to have it repaired or pay for it ourselves to have it couriered. I am situated in Midrand and find it unacceptable, if that's the case and this is the type of service I am going to receive, then I want a refund and they can have their device back. This is pathetic service from both FNB and Sony
