Bad service

I'm currently using the telkom uncapped data I set up a direct debit each month I was informed that they will no longer be taking payment via my account and I had to deposit the funds to their account details given to me I did so however I'm still receiving messages informing me that u have not made any payments and now I'm left with no internet connection yet I have paid for my subscription I'm an elderly lady and I just need my internet connection set back up as I have paid what was due
