Wifi not working

I have a mtn wifi router. I made a payment on the 25th of August 2024 and I called mtn on the 2nd of September 2024 and I was advised that my line will only be allocated on the 1of October 2024 because it shows that payment was made on the 26 of August so I accepted that because there was nothing I could do. Today is the 3rd of October 2024 and my wifi is still not working. I tried to call mtn several times on the 1st and on the 2nd of October 2024 but I was unsuccessful. I even send an email to one of their team leader or manager *** to ask her to assist me with my query but she has not responded yet. I went to mtn today shop to try and get assistance and Neo told me that I had to pay R14 due to late payment so I paid the amount and he told me that my wifi will be working when I get home but it's still not working. I want mtn to allow the router to work or they must give me back my money so that I can get another service provider. Mtn has poor service shame.
