Fed up with mtn

Hello Peter. My name is Elsie Ratsela my cellphone number is ***. Please post on my behalf. I have a bad experience with mtn via a contact cellphone I took 2years back. My contract ended on the 1st of October 2021 according to our agreement. They deducted again on the 1st of November & send airtime & data like as always. I called them to make them aware about that incident they promised to cancel on their system as agreed. Today at about 11h00 they send an sms saying that they will block my phone to never access any contact. They say I am owing them R110 of which is them who owes me money they deducted on the 1st of November. I am so disappointed about their services & the problem is you call them time to time they transfer you to next available consultant as always. The 1 untrained consultant did not do the work properly. I need nothing to do with this mtn company anymore 😒. Poor service & I also asked them to port back my cellphone number to vodacom. They must end my contract & port back my number. As for R110 I am not going to pay it.
