Poor customer service

I recently purchased a gas stove from Westcliff furnitures, upon installation the gas installer notified me that there is a factory default as 1 out of 4 burners were only working.

I then went to the store which I'll admit they tried to be helpful but also blamed the gas installer whom is accredited. We requested the direct line for ferre which we haven't received. The sales assistant then sent out an email to ferre which they have notified me that their technician gets back on Monday the 26th and will contact me to come out.

I am still waiting for the technician. I have received bad customer service from Westcliff furnitures and ferre which is disappointing!
