Horrible service with MTN

Good morning,

I would like to inform you about MTN South Africa, I took a cellphone contract with them in 2019, which ended in 2021 in May.

They wanted me to upgrade but I told them I don't need an upgrade, I just want to cancel the contract since I am no longer working, the consultant that I spoke to promised me that the contract has been canceled.

In June I noticed that MTN tried to debit my account for the contract that I thought was already canceled, I tried getting in touch with them a number of times, via calls, social media platforms, and their complaints department, but no one is willing to assist me

They have since blocked my number, and it's now almost 4 months.
