Please Pick Up Your Phones

I recently app**** for a contract at the canal walk branch and they told me that they would give me a call within 72 hours in connection to the application. That was last week Wednesday and to date l haven't heard anything from them. Thus I am no longer keen on getting a contract with Telkom anymore and l would like to cancel my application but Now l have been trying to get hold of the branch but the phone just keeps on ringing with no answer
