Poor service from fnb

Fnb is suppose to pay me back my money from a debit order I've stopped and evretime they tell me I must wait 40 days to get my money back. 60 days have lapsed and still not my money back!? Poor service from FNB. I stop debit orders then they still go off afterwards and when you reverse it it doesn't get reversed and you don't get your money back. When you call them you can't get through and I've waited 47 minutes on the Lin to speak to a consultant without success. Petrol card they said will automatically be activated within 48 hours which didn't happen and now they say I must dial a Tel. Dialed the NR and can't speak to a consultant. It's just impossible to deal with FNB. Worst bank ever with the worst service but I'm a private banker?? Private banker means nothing with this tyoe of service.
