Wrong Order

I ordered on the website. I received a call to query stuff that i added to my basket. I felt rushed to finalise the order. I was told that the items i was purchasing was almost gone and that the last 3 was available. Why was i not left to finalise my basket when i was ready. Why have the option of purchasing online if we going to have people calling to finalise purchases. I've now received the wrong colour. Ive tried calling with no success. I emailed and have been told to return the purchase and re-order. This wasnt my mistake. Why cant the correct colour be delivered and the wrong one collected on delivery. I dont want to have to be inconvenienced for someone elses mistake. And what if i cant get the colour i required? I want this resolved asap. I logged this previously and no one contacted me as promised
