Becoming just like Vox unreliable and ****mers

I've been calling rain, I called them 3 times yet my query is not resolved. I paid at pick n pay for the month of April because my bank card was stopped I paid the account short with R9, so they recorded it as I haven't paid them at all, I spend hours at a time on the phone you promise to call me back and never do. I have a promise to pay now on your rain go app which I'm now in a deficit. But I don't owe any money all I owe you is R9, I keep asking to speak to a south african consultant but all my efforts are in vain. The international consultants say they understand they see the payment and promise to get someone from the billing department to call me back and no one ever does. I've been on rain maybe 4 years now and it's really been convenient but now I don't think it's worth it anymore, customer service is everything to me. But this treatment is pathetic. Imagine having to pay double but I don't owe and not being called back to be assisted I have to beg to be assisted. Even my husbands rain account is in arrears but we called to cancel they still continued to charge for 3 months which doesn't make any sense because u have to pay in advance to use rain services and they switch the wifi off if you don't pay so nowadays yall seem to be like vox just ripping the people off for personal gain.
