COMPLAINT AGAINST MTN CONTRACT

I'm Lumka, Account number A*** had a contract, and my account was suspended in October 2024, and MTN continued billing me. On 14 April, I settled the account. On April 15, I sent an email canceling my contract. MTN is still billing me. I request the refund for the payments made from October to April 2025 because my account was suspended; therefore, no data was allocated. This is affecting my credit score.
