Failing to refund R450 wrongly paid to i***3

On the 22/12/2014 I paid an amount of R450.00 reference VODSTQVWSYFC to this account which is closed i*** - I realised I had paid to the wrong account when the debit order for my current top up contract for *** deducts. I then called Vodacom immediately when I received the sms and again on the 13th of January and was advised that they will refund the money and 082111 call centre had done nothing and **** to me. People on 1940 could not assist and gave me 1946 to call-and was even told Bonginkosi has received my request and will be making sure the payment is done within 7 days. Now counting from 13th of Jan I would say I was **** to again. Today I called and spoke to Vusi(female) on 1940 who said the call was closed but cannot se the results and advised that 1946 will assist. I called 1946 today and Tsholo answered and told me that she is in cust-care n cannot assist, I must dial the same number-because I was rerouted-I knew then Vodacom is playing games with its customers. I want my refund done on my fnb account asap-this has been over 3.5 months waiting for it. I can not wait for my curr top-up contract to end in September so I can leave this ****ty company
