My order on Hold

I have had it with Mr Price online. Whilst the rest of the world and other online stores in SA are excelling with online shopping. Mr Price online is going down the drain. I had previously complained about my order being shipped, than no longer being shipped as one of my items are no longer available. How is it possible to order items, pay for them, get an email that my order has been shipped. Then four hours later get an email that one of my items is no longer available. My emails go back and forth with one of the cons by the name of Delisha Aroomoogam who is very unhelpful and uses condescending words towards a customer. Today I go online to see what is available then I come across the jeans that they said are sold out are now available in the same size I tried calling them on their 0800 number, but nobody answered, I then send an email Mr Price.com again to query why they don't take the same Jean that is now available online in my size. But instead I get a response Delisha Aroomoogam surprisingly, don't know but is she the only one working there? . She still responds back to me with an attitude, even though she did ignore my last email to her on our last conversation. She tells me she can't replace, they don't replace orders and she has told me this before. That she will look for which store has the Jean and I must go to that store. Why would you put a customer through this, why must I run around like a headless chicken to Mr Price store for an order that is available online, this will defeat the purpose of online shopping. They could save the customer from all the frustration and take the available Jean which I have already paid for and Unhold my order and just ship it. Another helpful consultant by the name of Siphesihle once helped me by the same manner, she started out like Delisha but winded up helping me. This is really an inconvenience, it's not like I did not pay for my order. All I want is my order which I have paid for. This is really poor and bad service I have ever received from Mr Price.com
