Fed up with Rain Service

I have been trying to get Rain to reconnect my internet connection since I made payment on the 1st of May but to no avail. When I call I keep getting through to the same agent who I can barely understand because of his accent, and all he promises is that he will escalate my problem. Yet they keep trying to deduct the amount from my account. I have emailed the proof of payment to an email address provided by the said agent (***) yet this email does not even have an automated response to confirm receipt of one’s email. And when I asked to be transferred to a manager or the billing department, he tells me they cannot do transfers and will get someone to call me, but there still has been no call from anyone. I am not making another R625 payment when I have already paid it.
