USELESS and INCOMPETANT - paid deposit now holding back on delivery!!!

I did an online application which was approved spoke to Lebo and sent through all my documentation as per the request and got the final go-ahead she advised that I will however just need to pay a 10% deposit which was fine. I went to the Lewis Roodepoort store on Saturday and the service from the sales gentleman was ridicules. After deciding which double bed I went to pay the R800.00 deposit and all was fine asked if the delivery can take place the same day and they advised that I must first do the interview with someone from Head Office so delivery will take place on Monday. A gentleman called me on Saturday and we did the interview and he welcomed me to be a Lewis customer the final approval is done. This morning I got a call to ask if someone is home as my delivery is the first delivery that is going out this morning, then an hour later got a call asking that there is a hold on it as there is more paperwork needed that I must submit. I have had several calls this morning with Norah at Lewis Roodepoort. I am truly not happy with the service I have received from The store I want this delivery done today I already paid the deposit why take the deposit if everything has not been finalized. Get this sorted out ASAP with delivery TODAY!!!!!!
