I had lodged a complaint of Kaff Hob and first up they took ages to respond though they mention that they provide quick service & same day service and all those crap and there customer care does not have any sense of responsibility when customer checks for update of the technician visit.
Also there technicians does not have knowledge about the kaff HOB at all and they have spoilt the hob which is not working properly. Also they charge exorbitantly for the parts which is not even cleaned forget replacement. Please do not use there service.
