****ed/unhappy and very disappointed customer

Good day,

I am very furious on how you handle issues. Today i returned my Hisense microwave because it has been giving me issues. Burning smell coming out of the back and a lady called khululwa from the customer service department informed me that they will not be able to take it back because it is infested which is confusing because the issue is electrical and ****roaches would not be able damage the cables.. I fail to understand the process and this clearly says that you are advising that we should not return any items faulty and it is within the guarantee.

Please advise what should i do..

Unhappy customer
