Keep on requesting Documentation

I've been trying to get a credit increase since the 12th January 2015.<br> <br> Firstly the quote wasn't sent to me which I followed up and finally got it. I attached November and December payslips.<br> <br> I then got a mail that I need to send documentation they have not received November payslip.<br> <br> Send November and October because I'm a commission earner this email I send about 7 times.<br> <br> Now they said now The need January as well which I send through ones again 3 Months.<br> <br> I just received an email to send my docs again.<br> <br> Clearly it was a mistake to move over to this bank <br> <br> This will probably roll over to March which they will ask me to send it again
