Unauthorized debit order by Mtn sp

I would like to write a review about Mtn sp, They are **********ly deducting different amounts from my bank account.

It started on the 15th of February 2022, they did it on the same date in March 2022.This is inconveniencing. I never signed any contract with Mtn sp.

I would like this to stop.

Yours faithfully Simangele Dhladhla ***
