Waiting two months for refund

I paid funds R6000 into an account wrongfully linked to my name. The situation was investigated by another person at Tshwane Municipality. The mistake was discovered and refund was suggested, and approved by this person. Necessary papers for application for refund was submitted. Now I have been waiting two months for refund, and financial department is still not responding to this approved refund. I have gone so far as communicating with the Presidential hotline, and all e-mails just get forwarded, and nothing is happening!!! All the necessary proofs and documentation had been submitted. I am at my limit of forbearance! I have explained and explained.... What was meant to be a formality now seems to be a never ending delay!!!!
