Bad service, Incorrect Billing Refund refusal,

End of August I canceled the one product of my account. I was how ever then billed and requested it be rectified so I can make payment. I waited 3 to 4 days for a response. In this process I was forced to pay. The day after payment was made due to rain putting internet usage on hold due to none payment rain got back to me advising the issue has been rectified and that I should log in and make payment for which I was happy. Having already payed I requested a refund for the amount I was over charged. Thato Ramere was arguing with me continuously saying they can not refund me. I stated to him that I was notified the billing error was rectified so I pay my 699 and want a refund for 479 as per the resolve and rectification. After I have provided him with the reference number for the interactions he completely vanished and since Thursday didn't even bother to respond to my email. Needless to say I've logged another query and now on Wednesday still no response from anyone after the emails states 24 hour turn around time. How can rain blatantly "*****" from its customers by not refunding and arguing with no feedback in a week.

Reference numbers for interactions #*** - refusal of refund #*** - initial request to rectify billing
