REFUND

In May 2015 I phoned my bank to make payment arrangements and it was granted. AMOUNT THAT WE AGREED ON WAS R1650 & I was told that it will last for 3 months & it will begin in June to August 2015. To my surprise my account was DOUBLE DEBITED R1650 & R2424.20. I phoned collection department on Tuesday morning and I was advised that they will refund R2424.20 within 3 days REF No: *** was provided. On Thurday the 27/08 only R1650 was refunded with a defit ofn R774.20. The very same day on Thursday I phoned again requested to speak to Lebo Keetse and i couldnt get hold of an email was send to her and I was told she will call me at 10am and nothing happened, I made a call back after 2pm and I managed to get hold of her and she promised to call me back on Friday 12noon and she never kept her promise. I had to call the collection department and I was put on HOLD for 30 minutes and I ended up dropping the line. All I want is my R774.20.
