Pathetic Service from FNB

I have been banking with FNB for about 8 or more years now and I have recently had the worst service from FNB ever. I had requested my accounts to be downgraded about 3 to 4 weeks ago now. They said it would 5 to 10 working days to be contacted i only got contacted 3 weeks later after the initial request. Once contacted they said it would take 48 hours to get the quote that was almost a week ago now. Every time I speak to a consultant I get the whole excuse that its been escalated and so on and someone will contact me. Absolutely pathetic service from FNB I would not recommend FNB to anyone as the service you get is nothing more than useless.
