Faber — Hob malfunctioning

Address:

C1208 Paras Dews Sector 106 gurgaon

I purchased a HOB FROM FABER in Jan 2023 it was installed in March 2023.
This is the most horrible product i have purchased in my new house.
In first two months all the burners are worn out it seems I am using this product over a decade .replaced one burner also but rest three are in pathetic ...after not even one year use.with this hob my cylinder runs only for 15 days, before this my cylinder use to work for 1 month 15 days.have taken service (AMC) from Faber also.but nothing has work.ots seems like making the biggest mistake after purchasing this product
