Pathetic Online and Customer service

Absolutely terrible service. I tried to order a top online about 5 weeks ago. The website was not redirecting me to the payment gateway, so I was not able to pay. I tried Numerous times for about 5 days with no success. I emailed customer and online services numerous times about this error and I got dumb responses like "please purchase in store" etc. Then when I looked again, my size was sold out online. I checked which stores have it in stock as a last resort. I then phoned the store. first the number on the website was incorrect and the answering service gave me another number. I called that number and it just rang, no answer. I then phoned customer care and they informed me that the store did not have the top in my size anymore. Only store in Cape town (I am in the west of Johannesburg). Because of their bad online shopping service and online showing incorrect stock levels for stores, I now cannot go in store to buy the top either. I then asked the call center agent if they can send it from another store, and she said she can only do that if I have an account because they need to charge it before sending it. I asked if I can pay it upfront to get the top sent and she said I can't. That is an absolute pot of ****. ..what utterly bad service. If I am willing to pay for an item then you should be more than willing to send it for me. So so so disappointed in the "Big Name" retailer which is not willing to budge a mm.
