bad service which is affecting me financially

1. On 04 August 2019 at 08.45, I accidentally bought prepaid lights of R1000.00 instead of R100.00 using my Ned bank app. I immediately called Tshwane Municipality on this number ***, the lady who helped me gave me the following number to call during office hours Monday to Friday ***. On 05 August 2019 from 07:30 until 08:30 I called that number with no one answering. Then called again the *** the lady who answered told me she is escalating it and when I asked for reference she said there is none then gave me this number to check how far are they later 012 ***. 3. unfortunately my child's transport is not paid until today because they have not returned my cash and I have been calling everyday since with no answer. today the switchboard *** twice answered and I was transferred to hold for +- 30 with no one answering. 4. All I want is my cash back so I can pay for my child.
