Pathetic Server for over 6 Months

I logged a call in June 2017 with Whirlpool, Ticket no: 19136 My stove top was cracked, i waited 2 months for a replacement glass, the Technician Sam came out on 2 occasion with the wrong glass, eventually they asked me to go for another stove since they cannon get stock of the glass. Every week i call them and follow up to no avail. I eventually settled for a gas hob and made payment in full. I am still waiting for my stove, spoke to another lady today. She says that the order is standing and has not yet been put through. I am totally frustrated with Whirlpool, after 6 months i still am not given priority service, pathetic.
