Unfair billing

******ion and unfair billing by MTN. I recently enquired to upgrade my home internet contract (month to month), just to put it out there, I was informed that its not possible, will need to cancel the one I currently have and open a new one, nor could i migrate to a higher package that I was looking for. I did exactly what i was told to do, cancel it end of the month and open a new one. Which i perfectly grasped and executed as advised by MTN agents/consultants. To cut the story short, i was asked to pay upfront for the new contract, new connection fee, and pro rata data since i asked for the cancellation on the 28th January 2024. Condition for cancellation was you return the modem, sim card, chargers and lan cable. Which was done on the 28th Jan. Come the Mid-Feb 2024, i was billed and my account was debited, to my surprise, for two contracts, including the one that MTN Quagga centre has requested to be closed. I called in to enquire and i was taken from pillar to post and was blamed for the mess up. Now, i paid for the valid contract and my line was blocked and now i am made to pay for the so called still active, but the cancelled contract. They refuse to open my line until i pay the outstanding, but i did cause i am placed in the corner. My advise to anyone intending to take up this contract with MTN, be careful cause its a money making skeem which only prejudice its clients and money ******* by cutting any services you have with them in return for a payment. I am ambushed financially by this company which i respected a lot.
