Edgars Online Banking is a disaster

Buying from Edgars online is the worst mistake one could ever make. I placed an order for an essential product on the 2nd of May, at the time that I was placing an order, the website indicated that the delivery of essentials will take between 3-5 working days. Its week 3 and I still havent received the parcel that I desperately need. Their website is misleading, I was given an order number that I can use to track the delivery but their system doesn't recognize that number :-( There is an *** on the website, apparently you can use the number to track the order if you are battling with the system. I called that number on the 8th of 8th May....the answering machine answered, I was made to hold for 54 minutes only for the phone to be put down on my ear. I phone again on the 11th pf May, held on the phone for about 30 minutes and eventually gave up. I called again on the 12th of May - still there was no answer.I called again on the 13th, 15th and eventually someone picked up the call on the 18th of May. The lady advised that the parcel status is "picked", she couldn't explain what that means to me and asked me to wait until the 21 or 22nd latest. I calling again right now (21st) and I have been holding 37 minutes and counting. I have also filled the enquiry form on the website more than 4 times, each time getting an auto response to say that someone will call me within 48 hrs.....guess what 35 minutes later someone decided to take my call. The status now has apparently changed to "in warehouse" Edgars is not deserving of my money, please can someone call me as a matter of urgency as I would like to get a refund. This is very upsetting, especially because I am a paying customer. I have done online shopping with other shops and I never ever had such horrible experience.
