MAKRO SPRINGFIELD HISENSE MICROWAVES SHOCKING SERVICE

Purchased a hisense microwave in dec 2019 and now told that they cant help me because i changed the plug..really!! My cupboards are designed in a certain way hence the need to change the plug. Staff very unhelpful and l had to make a scene and was referred to a lady by the name of wendy who advised me that the unit had to assessed as she could see my frustration. Got told that sorry cant help me about 2 weeks later as plug changed. Was asked if i read manual to which i responded no and that i didnt think it would be a problem. No one told me on their sales floor that this will be a problem as its not even on the makro proof of purchase slip either. If this was R20000 fridge would the same apply and will i get told that the warranty is void . Will never shop at makro again or buy a hisense product ever again because both these organizations know nothing about service. BEING A MAKRO CUSTOMER FOR MANY YEARS MEANS NOTHING AS THE SERVICE IS PATHETIC
