Vodacom not paying my refund back

In September 2024 I took out a plug WIFI Contract with Vodacom in Vincent park mall (East London). I experience network challenges with the WIFI and on numerous occasions they requested me to restart and the WIFI did not work. In October they requested me to send the WIFI Router back to the store (Vincent Park) so that it can be sent for repairs and after a week I went to the store to fetch it and they told me that the Router was working. I too it home again and the router still did not work. I went back to the store again and I took it back to them again and they told me that they are experiencing issues with the router and they are upgrading their network coverage around the area I live in so they took the router again and informed me that I need to wait until the following Monday. On that Monday I went to the Vodacom shop to fetch the router I asked them to test it first and at the shop the router did not connect to my phone. The lady that assisted me stated that because there is no coverage the will cancel the contract because the router was not working. The cancellation was done on the second week of November and I was informed at the Store that I was going to receive a refund of R 494.53 after 14 working days. In December 23 I called again because the refund that was promised was not paid in my account they lady at the call center said the amount was credited to my account and I must sent an email to *** to inform that the I want the money to be paid directly in my bank account and that will be done in 3 working days and that did not happen. On the 06 January I called the customer service call center and spoke to Nondumiso and she was very sarcastic and she told that I need to go to the Vincent Vodacom Store in Vincent Park to get the refund. I then went to the store again and I was told at the store to call vodacom like I did before because only refunds department can refund the money. I called again and I was told to send the email again requesting that the money be paid in my account. I resent the email and until today, the refund is not paid in my account yet. I am very frustrated with the service I am experiencing with vodacom. I did not even enjoy any service from them. The worst part of it is that they are not paying the refund that is due to me instead they are sending back and forth for refund they know I am suppose to get.
