POOR SERVICE - CLOSE THIS BANK

I app**** for a bank loan almost 2 weeks ago, they approved me for R2500. Th next day I received a call saying there was an error on the system and I have been re-approved for R5000. I went back to fill out some more paperwork. The next day I was told to send in my documents which I already submitted and cost money to get e.g bank statements. I did as they asked and left. The next day I got called in to find out what was the delay only to be told of another requirement of a bank confirmation after providing them a stamped fnb bank statement. I went back in and provided it. They refused an fnb confirmation thats given to everyone in south Africa because it was not signed. I went bank to fnb and asked them to sign and state the position of signer something unheard off at fnb. I submitted and left. The weekend came and went with no word. Monday I call them to ask and am told my request was denied as they have linked my information and have to come in and re-apply. Now I have been approved for R12 500 and signed a 3rd set of papers at this bank. ITS ALMOST ANOTHER WEEKEND AND THERE IS NO CALL OR SMS OF WHAT THEY ARE REALLY DOING. POOR SERVICE AT ITS WORST. PLEASE HELP
