Month to month home Wifi

I app**** for a month to month home wifi package, where in the time I had the wifi I only had 8 hours of wifi, therefore a lack of service. I have been trying to cancel my wifi since the 6th of February 2025 and everytime I phoen them they ensure me that they will cancel the wifi. I have asked for a refund as well due to the fact that I have paid and had no wifi. On the 4th of March 2025 they deducted the payment again form my bank account I phoned them and informed them that I have reversed the payment and they said it was the right thing to do they will make sure that my cancelation will be handled. Yesterday I phoned them again and they tell me the cancelation is still not done and nobody has done the cancelation I need to go in store and do it there. Today I went back in store and they informated me that I need to pay the reversed payment otherwise the cancelation will not happen and if not paid MTN will deduct the router amount as well, which I feel is not fair because the router has already been send back on the 6th of February 2025. During this process I have received the cancelation number but a lack doing it. I would not recommend MTN to anyone because you will not get service.
