Terrible service

I'm so upset with fnb I have been such a loyal client of theirs for years, I had a query regarding my credit card, as they took out a sum of R2600 for payment in July, till date none of my statements are reflecting that amount as taken when u query it with several agents I was told the money is showing on their side and taken for the facility. I was given an email add to query, after sending my email I get feedback they received the money and its available on my credit card which is false!!! I even sent through the sms showing the amount that was taken. I requested a manager to call me and explain why none of my statements are reflecting that amount till date no response. Even last month a further R1100 was taken off and its not reflecting in the account. I feel so cheated by fnb and no seems to care to call and rectify this situation.!! I also qualified for a revolving credit on the 17th Oct I followed all the steps and the account had been created on my side but still having a balance of 0 available. I called on the 18th to find out what's going on they informed me to give the 3 working days as it was escalated and everything should be fine by Friday the 21st Oct. I called yest again as it was the 3rd day only to be told it's sitting with the people to approve and they escalated once again abs by end of day 5pm the money should be available. To my surprise nothing was still done I sitting with a new account with 0 balance?? What's the point of offering someone a product then when it's been accepted and account created you get told to wait for funds over a week?? With all my years in fnb this has to be the worst service ever!!! First they ***** your money and there is no trace of it from their side then they offer you credit facilities and don't alloc3you the funds!! If someone can assist me with my ****** money and show me proff it's gone towards my balance I would appreciate it!
