Pathetic service

I bought a stove in June, even took extended warranty on it. The stove became faulty on the 17th December 2018 I then called the service centre on the 20th. I was informed that thier service centres were closed , only opening on 7th January. Till today am without a stove. I've called several times they all say they will return my call . Till today I have not been assisted. I am highly disappointed at the service and the product.
