Rain on our parade....

This seemed to good to be true. September I couldn't pay my account so the 2nd November I paid the full amount that was outstanding R1916 and the new bill was dated for the 25th of November. I received my money on the 24th so I thought I would pay my account on the app. Now the website and the app says we haven't paid our account... So we phoned and the service provider requested a bank statement, so we sent the email and heard nothing back from rain. The following day we logged in to rain website and still that same problem. Phoned the service provided and the man I spoke too kept insisting I haven't paid the bill, this after I explained everything including that I have sent an email with my bank statement to prove I have paid. I'm considering to cancel both my rain cards. This is unacceptable. My ticket nr is. ***8 if this problem persists I'll have to cancel and move to another company as we work online and can't pay for a service that I don't get. Really unhappy about the service
