BAD SERVICE

1 bought a an elba gas stove from from builders warehousse. i installed it and found that there was a gas smell . i called my installer to check he said his installation was correct .theres a problem with the stove . i called builders . they requested coc and invoice which i sent to yassiem . i have since had no feedback from him . sent him many emails and tried calling to no avail . there service is really bad . definitely look at leroy merlin or other similar businnes . as BUILDERS are pathetic
