*****ing

I am very upset with this Company which cant help after THEY made the mistake. I have got 4 contracts with them. The main one needed to be renewed which I did. When going there they informed me I can only renew if I dont let them do a d/o, which is not a d/o but debit cheque. I agree to it and asked the d/o to go off on the 21st of the month. By the 28th they have not (what I believed a D/O should be) through my account. I decided to pay it because I did not want my phones to be cut. On the 30th they decided to put 2 debit cheques through on my account. Now I struggle to get them to refund me. 1st they needed proof they deducted (which should have been seen on my statement) then the query was closed because they did not receive it within 3 days I spoke to them the morning and send it the evening. When I called them again they needed prove of my banking account which I send to them. Then that was not enough they needed my bank statement. I send it but am not prepared to send my password to them. I do not know how to take the password off. I also feel they do not need to see my whole bank statement as ALL my transactions is on it as well as my balances. I feel like making a case of ***** against them and hope I will get my money back this way.
