Poor service/No feedback/Empty promises

6 Months ago mastercare fixed my fridge and now i am finding myself in the same situation again with the same problem, which raises questions in my mind what guarantee are they giving on there service, am i going to have to call them in every 6 mnths to replace the motor. Anyway i agreed they can go ahead and order the parts on 30 January 2015. It is now the 10 February and no one has gotten back to me i called them on the 4 February where they promised me that ph fridge will be repaired by the weekend. Another call made to there head office where there ph lines adv they are to busy and that we mst send an email. I phone again on another number and advised that the part has stil not arrived, WOW IF ONLY THEY LET ME KNOW, well i guess its another week i am gonna have to wait for my fridge to be repaired and once again a promise made that my fridge wil be ready by the weekend, but he doesnt have the party yet. RIDICULOUS SERVICE FROM MASTERCAR, EMPTY PROMISES AND STAFF WHO JST DONT CARD
