MTN Customer Service is dated.

I signed up for a SIM + ROUTER contract worth R499 online and on 12/02/2021, I received my package from DSV. I handed in the required documents upon delivery.

On 13/02/2021, I received an SMS confirming my new MTN number. I thought that indicated my sim was activated, but was still unable to use it. I called MTN and they said they'd look into it but nothing happened. I went on their Facebook page, messaged them about this and they said it's been escalated but still no joy. On 28/02/2021, I got an sms saying they were gonna debit my account R721 beginning of March, which is ridiculous for many reasons. First, I signed up for a 499 contract, why am I being debited 721? Second, through their unreliable customer service, I was stuck with a SIM and router I am unable to use. Why am I expected to pay for it in the first place? I am aware this will mess up my credit score, which is the major reason I took a contract to improve it, but I will not pay for this nonsense. For an ISP that's been around for some time, I expected they would be better equipped to handle this matter swiftly.
