Telkom mobile gone with my blackberry Q10

I had a problem with my blackberry Q10 so I went to telkom mobile at the east rand mall branch. It was the day of the 9th Feb. The said my phone was under warranty and if the problem was on their side the would replace my Q10 and deliver it in 21 days. So I waited. The 26th of Feb I received an sms on my wifes phone that said my Q10 was despached and would be delivered in 4 days. Monday the 2nd of march I went to te east rand mall to collect my Q10. When I came the branch was clossed and there was a notification that said the moved to a new location. No one knows where is the new location because it doesn't tell you on the notice. So then I decided to call costumer care. They can't help me and give me other numbers to dail that doesn't even work. Now my phone is gone! I have the proof that my phone was booked in but nobody can help me. I spoke to a person at the benoni branch but it was hopless. I will not recommend telkom mobile for my family and friends. Now I am sitting without a phone. And the 2nd of march I was on telkom mobiles site and left a complain but nobody called back. So what must I do?
