MyRainApp Backend error causing billing issues.

After trying to deal with this privately to no help: Reference Number: ***1 I'm unable to connect to the network right now Because of a backend issue with your application 'MyRainApp' where I cancelled the 100 MB upgrade and confirmed that it downgraded last month on the first of May when the amount I paid showed that it's been downgraded yet on the first of June it's back to 100 mbs and I have to pay for something I explicitly downgraded two months prior now I can't connect to the network even though I paid R484.50 because your team wasn't replying to my opened calls and where putting me on hold until I hung up and I wasn't getting any connection to the network, by the grace of God I got through with Phindile from your team to help me escalate the matter to the billing department (Reference Number: ***1) she was great help but now billing department has not attended to the issue I tried to call now but wasted my Airtime of R20 on waiting for an agent to answer my call . Change my billing to R84.50 (R569 minus R484.50 = R84.50) That should be my new bill on the app please and thank you.
