Competent service, lack of communication, unprofessional service

Apparently, rain has not been debiting my account for a while however; I was never made aware until on the day my service was suspended. I phoned to enquire and I was advised I owed a 1000. I made the payment directly into their account, my service were reinstated. The same happened after 2 months; I made the payment again into their account. This seemed to not have been a problem since they managed to track the payment and allocate it correctly then re-instates the services. About three weeks ago I was contacted by an agent who goes by the name of Josteline Sematla, she advised I owed 1500 and qualify for the 50% reduction on my entire debt. I told her I’ll make the payment on my pay day, which is what I did and sent her the POP. The lady never got back to me since then. I started making phone calls to their call centre and was advised to send the POP, which is what I did only for their support line (***) to return unsent message. I phoned to alert them, they advised I reply on the email they will send. The same email address still bounced. I made futher calls and spoke to a gentlemen by the name of Kholofelo, who advised I sent the email to her direct line. I did as asked but nothing was ever done since. I got frustrated and send email that I want to cancel my subscription since I am being ignored and have to pay for service that is not rendered. If they wanted me to pay the remainder of the outstanding fee, they could have advised but there has been no word from them. Josteline only rep**** by requesting documents, I sent her the documents, she has went mute again, I have followed up but nothing. I am really tired, this causing me stress since I am working from and dependent on the service, the least they could do is to then cancel, so I could subscribe with another company because they clearly don’t want my business I frustrated, I am angry at the level of unprofessionalism.
