Russells & Russells warehouse - delivery

Utterly dissapointed with Russells amd the Russells warehouse about delivery of a product that needed to be delivered to me. I went instore to urgently purchase a study desk for my daughter, and the desk that was advertised on special was not in stock, which is against the CPA!!!!!! So they said it will be delivered to me. I then purchased the desk and also paid for it to be delivered. I dont know why I should pay for it yo be delivered when I went to the store woth my bakkie tk buy and transport the item that was marked on special but not available..... Russells sent me a msg saying the desk will be delivered on 24 June. They called me for delivery, when I answered nobody spoke. I tried calling back several times, nobody answered. I then spoke with the sales person at Russells and they also couldnt get hold of the delivery. They then sent me a message today sayimg that my order, which I paid for, will only be delivered on 28 June. This is unacceptable. Then I contacted the Russells warehouse, gave them my ref number amd they said someone would call me. Still waiting... I wont refer anybody to Russells. Absolutely pathetic
