Still no word back on my phone

My contract was previously with Nashua and it was taken over by Vodacom.<br> <br> I took my phone in over a week ago for repairs and i was informed that they first have to get confirmation from Nashua office that I am a client, fair enough, and was informed that this would take 2-3 day. I tried calling in four days later and there was no answer on the phone, after numerous attempts. So I went in the same day and waited an hour for them to tell me they still waiting for confirmation. It's now the following week, I've tried calling again and there is still no answer. Am I to go in now again and wait an hour to hear that they still waiting.<br> <br> I provided an alternative number they can contact me on but I haven't heard anything, that is why I am following up myself.
