**** and rude consultant

I had a contract with MTN on the 22/06/2021 for 24 months to months and the contract came to an end on 22/06/2023 however I have discovered that contract continued without my consent or without me being notified, I came to realized this when I wanted to take a credit and I was advised that my name is in default with MTN, I then contacted the call centre however I was not assisted, I was only advised to visit the branch when I arrived at the branch, they advised me to contact the contact centre again and the consultant who was assist me, she was very rude. I then explained to her that how can I contact the contact centre whereas I was referred to the branch, she did not even bother to contact the contact centre to find out what could be problem, she just provided me with the same contact number that I’ve been calling with no help, now I feel helpless as nothing was communicated to me with regards to extending my contract without my knowledge and now my credit score has been affected due to MTN.
