MTN INSURANCE PATHETIC

I cancelled my insurance a year ago with proof of payment and calener month cancellation. a year later again i had to pay and cancelled 2 months again and paid the full amount. got emails and SMS to say they must cancell my insurance. My ITC bad because of their negligence. Still, they have not corrected my account as I paid on 16 August 2024 immediate payment. And they still invoice me now for September. ***!
