Takelot unacceptable bussiness practice

Takelot send me the wrong size and color heaboard that i bought on special from them. They claim out of stock while the wrong item was send in 1st place. Several emails was send to several persons as everytime there is a new person working on the query not having any knowledge of previous correspondance. Everyone just doing their own thing. Promising to escalate and never following up. Just ignoring all correspondance. When enquiring to contact details of the supplier as well as takelot ceo details. Just passing credit without supplying any contact details or trying to resolve error from their side. Unacceptable practice
