Poor customer service

Good Day

This is my second follow up on email and have also done telephonic follow up at MTN ,5 times.

I have app**** for an MTN home router on 15 August 2024 and was told it has been approved . I was sent a link to make payment which I did. After four working days i called MTN to enquire about the status of when i will receive the router and was then told that the application was declined even though on the 15th i was told it has been approved and also received sms from MTN confirming approval. I then requested for my refund on 21 August 2024 and was told to send an email which I did, copy of the email is below on the trail of this mail. On Friday the 23rd, i called MTN to follow up again as no one was contacting me, and was told i should wait for Monday the courier will call, and was told there was an error on the system as my application is reflecting that it has been approved not cancelled. Today 28 August 2024 I called MTn again for follow up and I'm told the application has been cancelled. I have requested that they refund my money which I paid on the 15th of August but now I am being sent to this person and I keep repeating the story to all the consultants that I am being posted to. Can someone take responsibility and advise me when I will get my refund and it seems no one wants to account for my refund.
