Pathetic Service

I bought a cellphone online and about a month later, then phone starts freezing, so i returned it to the Hi Store in V&A Waterfront. From the day I went there the consultant gave me false information about the procedure (said the phone would be taken for repairs the same but ended being informed that the phone was taken for repairs about 5 days later. That obviously meant that I was going to wait longer than what I told. Bearing in mind that I bought the phone for someone who is seeking employment who has probably missed a lot of chances due to not being contactable. Time went by and I got a call from the store but could not answer at the time but when I called back I told that the guy who called is not there (he's on leave or something) and no one else could help me till he comes back from leave as no one knows anything about my phone but him. I called back on the day he was supposedly back from leave and I was fed the same tale. A few days later I managed to get hold of him only for him to tell me the phone is there already (more time wasted for the person I bought the phone for). Now 2 days after getting the "fixed" phone it's starts doing exactly the same thing it was brought in for and I'm supposed to now again take time, and money, and go through the same process whereas it is Hi Online who sold me a problematic phone? I want them to not only fix this but to give me a new phone as I cannot accept this level of poor service. \

The person I bought the phone now has to wait another "21 working days" without being contactable for their faulty phone, That's not acceptable. And I want them to courier the phone to me, petrol is expensive for me to drive around doing this over and over again.
