Disgusting Service

I bought a gas stove from Lewis Stores about a month ago,i only connected the gas cylinder to the stove this past weekend. There no flow of gas to the gas stove. i contacted Lewis Stores ,Oxford Street ,Eastlondon on Monday by Wednesday i had no feed back i called Wednesday Monica the BM who i spoke to said someone be out at 9:00am Thursday at 9:30am noone showed up by now i am frustrated i call she says when the bakkie is free she will send someone. The call center then says its going to take another 2 to 3 working days. So i am inconvenienced by an *********** BM,who does not have customer servicing experience. I should of known their service was bad from me fighting for delivery of my items i bought when i threatened to cancel the contract my delivery was prompt. My complaint that i laid from the start was to the BM ,MONICA. Why do i have to wait a week for something that was reported on time.
