Might be your Battery or Gas, 'Mam.... (but all other plates are working perfectly!)

I wish it didn't come to this... but here we are! Bought a gas stove. Worked well, but within guarantee time, one plate stops working. Phoned installer. Installer says, phone Product Supplier: Delta Gas directly. Delta Gas came - fixed plate - left. One month later - plate dead. Phoned Delta Gas directly - Delta Gassays installer needs to fix.... -Wait for installer. Installer came to fix (let's put a stick into your plate's knob)... *@#@#@#* One month later, plate is dead - Phone installer - O, please phone supplier directly - Tell Delta Gas your problem - Phoned Delta Gas - we will come to fix, but don't do replacement. Delta Gas arrived - (outside the time agreed upon) - wanted to point out battery and gas - but all other plates work.....@$#@*.... Rep**** - we will replace knob for you..... 30minutes later - plate dead!!! No way!!! This is a faulty unit and needs replacement. Clearly no technician knows the fault. Delta Gas - please provide us with a solution.... Your service is below standard!!
