"Untraceable" documents, frustrated client

I app**** for an overdraft limit increase last Thursday and was approved. I sent back the digitally signed quotation the next morning as requested, but the funds have not reflected yet.

I called back yesterday to follow up and I was told that my documents cannot be traced on the system, even though I rep**** directly to the email address that sent me the quotation. I sent them again as instructed and still have not heard back. This is quite frustrating and I didn't want to resort to making a complaint on Hello Peter to get this resolved, but I have no alternative.

The consultants on the Secure Chat have not been very helpful as they have been giving me conflicting info regarding the turnaround time.
