Debit order canceled without consent, now im in debt.

I received a call from a company called MBD, relating to my Totalsports account. This company informed me that they have taken over my account due to non payment.

I explained to them that the account is being paid by my mother by debit order and this agreement was set almost two years ago ,while i wasnt working.

When i started my new job, i went to Foshini in Centurion to arrange a new payment plan, but i was told that as i did not have my card with me, they could not set the payment arrangement.

I then asked for a new card but was told that it takes too long and im better off looking for my old one. This was all in store. During this time my mother's account was still being debited and to our knowledge still is, as the payment arrangements were never canceled by us.

It has now being brought to my attention that the last payment made towards the account was in December of 2019. I was never made aware of this, for payments not to go through for almost a year, without being notified is unfair and unacceptable. This has now had a negative impact on my credit score.

I would like to file an official complaint and for this to be dealt with the utmost urgency. I would like to know when ,why and by whom was the debit order arrangements canceled, why was i not made aware of it .
