Poor service

I bought a touch screen whirlpool hop on the 30th of September and they said it has a guarantee of 2 years and I can extend it which I did. They also said I must call them if the hob gives me problems they will send a technician to come and fix it. I called on Sunday and reported that the hob is not working and they said they will send a technician. I have been waiting for the technician since Sunday, I called again yesterday and the lady that I spoke to said she will escalate the matter. I am still waiting. I regret buying from Makro. Their service is very bad.
