Hi-Fi Corporation sucks

Hifi corporation is the worse shop I would not advice anyone to buy from them. There products sucks yesterday I bought a television by hifi corporation in Kenilworth . The guy helping me was soo slow.... I got home television wasn't working properly this morning I took it back only for them to tell me they do not have cash to refund me and that they will let me know when they have cash this evening I phoned and they told me they only made a R500 for the whole day which I think is a lie . This is not the first product that is faulty of hifi corporation I would not advice anyone to purchase any product at hifi corporation
