The company who doesn't care

I logged a complaint regarding my laptop I got a call and then nothing so I called in and used 150 rand worth of airtime spoke to 2 people that said they are managers and will call me the next day. Guess what it's gone 3 days and I've recieved no call from them that's the kind of staff and managers fnb has. This is the worst service I've ever recieved how can you trust a company that employs ***** no one knows anything on what's going on and are all lost there's no communication and no feedback <br>
