Please can I get help from someone that will help!

On Thursday I app**** for a loan on the mobi site needles to say after emailing for help as the option is given, phoned 3 times on Friday with no help received either. I got an email this morning stating that my application expired. i Then tried to reapply and the system told me I can't reapply as I have an active loan which is not the case. i once again contacted customer care and was blatantly told to use the normal site. If I had access to the normal site don't you think i would have used it in the first place?????? What is the mobile site there for, ????
