ISmart incompetence

Good morning Im just out of my mind at this momment cause of iSmart its like u get this hope of someone is listening and does care but noooooo!! I curse the day i answered a call from them..after i wrote to hello Peter i got a call from kayla promising to investigate my problem with them handing my account to debt collectors while a debit order is going through every month from my account . She asked for my bank statements i did exactly that she called i explained to her everything for a second i really hope it will be sorted but nop yesterday i got a call from debt collectors with the same problem i told them im talking to ismart abour that cause i am paying them .i send an email to Kayla she rep**** asking for bank statements AGAIN !!! I responded asking what statement cause i send statement to her ? NO response and i send and an email asking a way forward got a response she wont be in a office for sometime.. So now what?? Cause these debt collectors are really annoying me. I can not continue paying not knowing whose taking my money if iSmart is claiming is not seeing it from their bank account. Please sort these nonsense.
