Paid twice due to MTN error, ignoring my repeated requests for a refund

On 1 March, I received an SMS threatening me to cut off my number after the debit order for February didn't go off. This turned out to be a bungle by the clowns running the MTN circus, as they admitted in an SMS 2 days later. On the night of 1 March, my debit order did go off. I also, early the morning of the 1st, made a payment in excess of R2000 using EFT, just in case. So I've paid twice, due to the clowns in the MTN circus being unable to get their act together.

Since then, I've sent MULTIPLE complaints demanding a refund to their alleged help line, and also phoned their alleged call centre. I was told that I'd get a response within 48 hours, but, needless to say, all my written and telephonic inquiries have just been completely ignored. No refund forthcoming either.

Now, this morning, I get ANOTHER one of the same idiotic original SMS's, alleging my account hasn't been paid. NO, you clowns, I've PAID TWICE. And now, once again, you're threatening to cut my off, after I've paid TWICE.

What a gigantic, *********** circus!
