Incorrect Billing - Pathetic SERVICE

The billing on my account is incorrect. I made a payment on 04 January 2025 and it still shows I have a outstanding balance. I have talked with so many people and no one is able to help me. Today I spoke with two ladies, both could not assist me but I was phoning the billing department.... ***********. I'm so frustrated because I don't have internet and I need to work.

The one lady promised her Manager will call me immediately but still NO CALL!!
