Shocking Service

I assisted my elderly grandmother who is sickly and has a broken foot in buying a new phone from HiFi Corporation. The phone was faulty and we went before the 14 days to ask for assistance and voice our concerns to the staff. They brushed our concerns off and sent us back home. The call quality is very bad, it sounds very distorted and it keeps switching off during her phone calls. We went back again and they brushed it off again, making an elaborate story about her SIM card causing connection issues (which has never happened before on her old phone). They recommended we buy a new one and so my grandmother spent even more money buying a new one which gave her the exact same issues. We went back for a third time and asked for a refund but they refused, saying that it was past the 14 days. They tested the phone there and it worked fine but when anyone else calls her the call quality varies and eventually becomes very poor. We spoke to the manager and he was very unhelpful and unsympathetic of my grandmother's situation. Do not shop at this business. We will never support any HiFi Corporation again.
