Incorrect Statement for 3 Months now - Very poor Customer Service

Good day

This is my final request to fix my billing statement that is reflecting R938 outstanding. I have now requested for 3 months to have it fixed. My premium for Jul and Aug were R963 as per the increase letter received by email and that was sent to yourselves many times, yet your invoice states R1058. If this is not fixed by the end of September, I will cancel my internet Service with you. The lack of response when lodging a complaint or requsting service is below poor. I was even contacted a month ago by an Agent and she said she would fix it, nothing been done. Final and last request. I dont need your poor and unacceptable service in my life. And when I cancel my month to month contract, know that I will report this to the Ombudsman because u could not resolve a lousy account of R190 that was billed incorrectly.
