Rain took my money

The orginal debtor order has run successfully for the last year on the 25th of every month. LAST WEEKEND I was trying to change my email address and I was locked out from Sunday until Monday morning from my account. I spoke to a sales agent to upgrade my package from 4G to 5G and he assured me that Rain would not debit me as my monthly payment had already been paid and i would only be charged the 5G package on the 25th of March. When they put me through the support centre a lady accessed my account with my permission to change my email address. To my horror, this morning a payment has been taken off without my permission of the same price that was paid on the 25th of the 4G package. I sent 4 emails and phoned 5 times before I got through to the support centre. A supervisor accused me of changing my detor order from the 25th to the 1st when I was locked out of the account for two days. He promised at lunch time that he would contact me with a solution after two hours because he has to speak to someone in management but has not managed to contact me as promised as it is end of business day. Rain has not been able to prove that I changed the debtor order to the 1st when I didn't not by many electornic or call recording. I did not instruct anyone to change the date. I feel vailated and mistreated by a company that I have supported for a year that would enable themselves to take an unauthorized payment double payment from my account. I will never recommend this company to anyone .
