NOT WANTING TO BOOK IN MY IPHONE 5s

I have had one of the worst experiences with the Telkom stores (CBD and Canal Walk). My Iphone has a problem with the network. It has been showing no service as signal, meaning i can receive or make calls, receive or send sms's for over a week now.<br> There first assumption was that there might be a problem with the SIM card. After numerous attempts (more than 4) at a SIM swap, i have still not been able to use my phone. <br> I arrive at the canal walk store last night (after having come there 2 previous times already) only to be told I cannot book my Iphone in for repairs unless i have the HARD COPY of the contract. <br> Now i have to go back there with the hard copy of my contract (which is less than six months old) before they will book in the phone for repairs.
