MTN failure to cancel contract

Good day,

I have experienced my number being blocked for a few days now. And I don’t understand why that is.

In November last year, I has an option to either early upgrade my S22, to an S25, ***) which happened, (Thank you for that).

But on the other hand, my *** number (data contract) was also coming to an end, and an upgrade was offered. I declined this offer.

This morning, MTN called, stating that I haven’t paid my account for over 2 months. This being the 078 number. Now, on the call, when an upgrade was offered, and I declined an upgrade, it was stated that this contract would be cancelled. Hence no debit order was in place.

My concerns:

I clearly rejected the upgrade, and requested cancellation. As far as I know, that took place Both my numbers are blocked, so I cannot use any of them (I need my phone and data for work) MTN only called me concerning my one number being in arrears, (A new debit order fell into effect,)

Now MTN is kindly offering a payment arrangement. What for? This contract was supposed to be cancelled as clearly agreed 3-4 months ago, yet I am sitting with the debt?

Can someone please sort this out. I have done my part, I have requested for cancellation yet it wasn’t done.

Why am I resposible?
