16 days for a Credit Application

I app**** for credit to purchase items @ Hifi Corp Fourways on the 2 Dec 2015. It took 3 hours waiting to complete the application which the consultant had submitted it twice it to their HO. their finance dept to have responded by the 3 Dec 2015. No response on Thurs, Fri, Sat nor Sun, Mon 7 Dec called in and still no feedback. Wed 9 Dec, the Hifi Corp in-store credit consultant said he had to resubmit the application as documents were missing. I resubmitted them again. Sat called into the Customer Call Centre & they wouldn't speak to a customer, that the customer needed to call the store & the store will give the customer feed back. After speaking to the supervisor they came back to me on Sat saying documents are missing but couldn't say which documents. Mon 14 Dec they needed a new bank statement, additional salary slips still no response. Then they couldn't get hold of me as they captured my number incorrectly. Tues hoped all had be logged properly - Thurs 17 Dec I got a call from the HO with an approval. This morning -its decline. This is the 1st I've heard that an application takes so long. today I await feedback from Store manager to advise why the different responses.
