Poor on line shopping

I ordered 2 pairs of jeans online, so that I could benefit from the promotion they were offering on the purchase of 2 pairs with a courier cost of R125. The wrong size was delivered. I took them back to Miladys Benmore, who told me to contact Customer Srevice who would sort it out.. Well, that was a waste of airtime as the lady made no effort to assist. She told me the jeans were sold out, but they are still available online??She told me I had to go back to Miladys Benmore; to return the jeans It took them over 30minutes to refund my money. They told me I must reorder online if I want the jeans. Only problem with that is that the courier service costs R125, which I have paid once to receive the wrong jeans. Now they expect me to pay it again.? ., What a insult. Many other stores sell jeans Milady's you have lost a loyal customer.
