Worst service with no customer service whats so ever!

I took out a month to month contract with Rain and was charged a prorata fee that also included their device. When i took up the contract i was informed that they will send me a link to make a payment. 1st December, i was supposed to make a payment but the link was only sent around the 3rd of 4th. I hadn’t been paid at that time and so the service (internet) was suspended. 11 December they went into my account and debited money which to my surprise i never provided them with my banking details let alone authorise a debit order. I called the customer service line and spoke to Phumla who didn’t assist in any way and ended up putting on hold for over 15 mins. I called again same day and spoke to Salestine who said the he make a request to the billing department to call me back and process the refund. 14th December i call to ask for any feedback as no communication has been made to me. I spoke to a lady, who then confirmed that the request was made and i should provide my banking details so that they can process my refund. I told her that Rain should have my account number since all the consultants that i have spoken to insist that i gave them my banking details and authorised the debit order ( which never happened). I requested the consultant to send me the call (audio) where I specifically gave them my account number and asked them to schedule a debit order. She then told me to go on their website and change my details as they will continue to debit whether i like it or not. I requested to speak to her supervisor or manager and after about 10 mins or so she gave the phone to Imkhitha who introduced herself as the supervisor. I explained my issue again to Imkhitha and she told me that they was no request done to the billing department (meaning all the previous consultants have been lying to me). She further told me that they will have to investigate as i insisted that when i took up the contract i was told that i would make the payment but to my surprise my account has been debited. So which means when you make the online purchase of the device, they save your details and later debit. I explained that the money thag was debit did not belong to me as it was sent to me to purchase something for a family member and that I haven’t been paid so i would need the money back. She basically told me that there’s nothing to do about this matter and hung up on me. Rain had blindsided me, i never approved or scheduled a debit order let alone provided them with my account number for them to debit. Im so disappointed at how their consultants (except for Selastine) have been uninterested let alone not eager to help. I wouldn’t recommend this ISP to any one because all they care about is money and not providing a good service. When you request the Audio of calls between you and them, they tell you that they cannot provide you with that, it’s against their policy but they keep saying all calls are recorded and are available to you upon request. What a disappointment.
