TURNAROUND TIME FOR LIMIT INCREASE

i app**** for a limit increase on friday, I sent all my documents that was required. I then called in on Monday and was told they cannot see when or if my documents are received, because I wanted to know if they can escalate it so that I can get an outcome, i have written my ID number on all the documents. and then I was told I must call in on wednesday afternoon for the latest to hear about the outcome. please can someone just have a look at what is going on here. it is urgent.
