FNB smart device department useless

I have had the absolute worst experience wit FNB's smart devices department. Within two months of receiving the smart device I realised there was a probkem with the charging mechanism. I immediately got in contact with smart device department and was informed of what the procedure etc was of collection and other t&c's. It took the service centre almost 6 weeks to come collect the device after phoning to complain that no one as collected, I'm still paying for the device and unable to use it. It then took another 2 week for collection to occur. Two months go by and I don't hear anything from the service centre or from Fnb smart device department, so once again I need to phone and follow up. Within 24hours of very upset call did I get notice that the device is faulty, I'll be contacted by someone on the way forward. 2 weeks later I receive 3 phone calls and shirty email, we can't get hold of you would you like a replacement. I rep**** to that email quite promptly that I prefer a refund and have heard nothing once again, another week goes by and I find myslef phoning and following up again on the matter. I was informed that by the close of bussines I would receive a call and guess what.... Almost 2 weeks later again and still... Nothing.... Extremely poor customer service from Fnb smart device department and the service centre that they in connection with!!! To put a cherry on the cake I'm still currently being debited for said device. A refund with interest would be the best solution here.
