Dissatisfied long term mnt customer

I am very disappointed with the mtn telesales department, I was called by one of the consultants to take a contract, I told him that I did have an existing one he told me that my contract was about to expire, so I agreed to take the contact, this month I debited for my previous contract which me question why, when I called in they said that my existing contract only expires in July 2025, i have been trying to get the new contract canceled, I get patched thru to different departments, I live in a one street town with no access to an mtn store, I feel very deceived by what the consultant told me. I have had very little help from the mtn call center in achieving this cancelation... Makes me want to move to another cellphone carrier
