Complain against MTN

I would like to report my dissatisfaction with MTN. On the 26th of May an agent called me to sell me the home router and I took it. Paid in advance for May and June. I received it on the 29th of May and it only worked on the 30th and 31st May 2025. On the 1st of June I called customer care and they told me that there is no coverage in my area and must return the router to the shop for cancellation. I went to the the shop on the 2nd in Empangeni and they said they can’t cancel it for me because i bought it online and there is a refund due to me, I must speak to online people that sold me router they are only going to take it in and send it to their warehouse. They gave me a copy of the return document with the IRMS number then I called the call centre on the 4th of June and gave in the IRMS number for cancellation. Lydia told me it will take 7-10 working for cancellation and refund. Till today the 13th of July the contract is not cancelled and they billed my again on the 17th of June, I don’t know for what! As it stands I need my refund and this contract cancelled. I did not use it because the agent confirmed coverage in my area and it turns out that is not the case. I am tired of calling MTN and being the run around all the time! I am wasting a lot of airtime calling your call centre everyday and not get assistance. I need someone to resolve this for me ASAP
