Shocking Customer Services

When I placed my last order I put in my address and it was correct. Then when my parcel was supposed to be delivered the courier Company Dawn Wing said it was incorrect, so I phoned Mr Price last week Monday and gave the right address again. When I phoned on Tuesday, they said it takes 48 hours to update address with Courier Company. I phoned in Thursday, was placed on hold and got no answers. I phoned in on Friday and spoke to Sindisiwe who put me on hold again and said she would phone me back, but did not. Now today when I tracked my order online it said they were returning my parcel. I then phoned in and spoke to Courtney, she said she will sort it and get back with feedback, but again no one bothers. From where I stand there is only two ways to sort this out to my satisfaction and that is either get Dawn Wing to deliver the parcel, or if it gets returned to Mr Price apart from crediting my account, I want a R100.00 gift voucher, as that is why I placed an order, I was given a R100.00 discount.
