NO FEEDBACK IN OVER A MONTH!

I purchased a Sony Ericson Experia E1 handset from Telkom on contract on the 21st November, 2014. On the 7th of March, 2015 I was sending a text message when the phone starting buzzing. I switched it off and removed the battery. I handed the phone into Telkom in Hemingways Mall to a lady named Asanda on the 08/03/2015. I was told it would take approximately 3 weeks to repair it. . I went in on the 21/03/2015 to inquire as to any progress and they told me that there was no progress to report but that it was with the Technician. I am STILL waiting for them to contact me with any sort of update about my phone. I have phoned the branch on numerous occasions but no one answers the phones. I then managed to get hold of the branch manager's cell number but he keeps promising to call me back and never does. Now he doesn't answer my calls either. I AM NOT A HAPPY CUSTOMER AND I REGRET DOING BUSINESS WITH TELKOM.
