Unprofessional staff, extremely bad service.

My dad bought a phone on 25/09/28 at house and home for R300 cash, because our landline wasn't working at home. We tested it as soon as we came home and it was working, it shows it has no signal and there is no dialling tone or anything. I called Telkom our service provider and they said that there is a problem with our line and it is not our phone. I returned the phone in it original packaging, in perfect condition.. I was served by Nelia. Immediately when she heard that I want a refund, she didn't have enough money to give me and that I had to come back. I spoke to a few other staff, no one was able to help me. Such a big shop without cash. Next excuse she came up with was that I need a ID since it wasn't me that bought the phone. Which is quite stupid because the phone was bought cash. Futher a other lady said that \we could've picked the phone up and head office need a ID copy". How does one pick a brand new phone up with the slip stapled to the box? I asked to see the manager She called her superviser Lizzy which wasn't of any help either. Walked back home got my ID after wasting 45 min there. Went back"
