RAIN sucks

I've had my account with RAIN for 5 years, and the account gets paid monthly via debit order. On the second of this month I got a message saying that my account is in arrears, and I need to make a payment. I checked my bank statements for the previous 2 months, and saw that the debit order is pulled on the 3 or 4th, so I ignored this, thinking the money will go through the next or following day. On the 6th I realised my data is not working, and logged into my account with them, but got stuck on one page saying I need to pay. I could not get into my data usage or anything else. I then contacted my bank to find out why the debit order did not go through, and they said it was never pulled from RAIN's side, hence it was not paid. I then decided to cancel my subscription, since they stopped my data due to their own mistake, but was again trapped on the page demanding me to pay. I then got hold of a consultant, first trying to check if I used any data for the month, which he claimed he cannot do as I must do it via my account. I then asked him to cancel my subscription, as their service clearly sucks. He said he cannot do it, but will forward my request to the service department. At 09.:02 on the 6th I received an e-mail, quoting Reference Number: ***1, saying an agent will get in touch with me. To date no contact.
