Bad service

We purchased a hisence fridge in Oct this year. After a few weeks I went to the store to complain the fridge is troubling. I was told a technician Wil cum out an I did advice that I wud prefer to hve the fridge returned an I Wil add more money to buy another make. The technician did come home after a day's. The fridge continued giving us problems. I went again an complained an was told its a Saturday an the mater Wil be attendant to on Monday. I waited an nuthing happen. I made numerous calls an cudnt get hold of anyone cos no one picks up. I went again an I spoke to them an was told they Wil send an e mail for hisence to credit me... An they Wil send a technician. Until today no one has came, I sent out e mails an no one responsed. For a huge reputatiable company it's disappointing. An to cum to of it makro has just opened a few months ago an dis is the customer service they give
