DISHONEST BUSINESS BAD AS HELL

I cancelled my month on month agreement with Rain BEFORE THE END OF SEPTEMBER 2020 and did not use any data services of them for the month of October 2020. Beginning November they charged R479.00(MONTHLY SUBSCRIPTION) against my current account for services I did NOT USE. After claiming a refund they told me that they cannot refund me because there is an invoice for October 2020. I requsest them for prove that I used theior data services for October but they keep on sending just the invoice and no actual prove that I used their serviced during October. Up till now I have not received any positive response from them regarding the refund. This happened to a collegue of mine also few months ago and she also had to battle to get her refund so it seems like it is normal for them to ***** people out of their money and charge them for service which was not rendered. They are bad, unprofessional and dishonest in the way they do business. They dont publish or provide a telephone number where one can contact them and you must do everything through the dash board on their website.The e-mail address I get reply from is: rain Customer Support <***>
