Double debit

I joined Rain with hope that everything will be perfect however its all just a nightmare, even the consultants do not have any answers to my questions. On the month of June Rain debited twice from my bank account, it was the 25th and 26th of June, immediately after seeing that I contacted Rain and I was told to submit proof of payment which in this case was my bank statement. I submitted the statement however they said I need to wait for the funds to clear. Funds did clear and I was told to email the statement to an email I was given which is *** on the 1st of July and I waited for response and there was none. I contacted rain again on the 12 of July only to be told that the email I used is incorrect and I was given a new email to send the statement to which is *** with ref ***8. I still have not received any update since the 12th and when I called today, the consultant I spoke to could not provide me with any feedback. Today is my payment date and how will I pay whereas I was charged twice last month. Can someone please attend to my case as this is frustrating me and also putting me on a financial strain.
