Stop holding my phone hostage!!!

I submitted my phone for a possible claim on the 4th of July, after calling in a few times and visiting your Mall@55 Telkom store even more times I finally received a quotation for an access amount on the 6th of August. I rejected the quotation and have requested for my phone back. It's been over a month now, week after week; agent after agent, visiting the Telkom store week in and week out (including today), it seems you have now decided to hold my phone hostage. Even the store has sent emails to escalate the issue with no response. The standard response from the call centre is "we are waiting for the repair centre to release the phone, it will be in store next week". Will "next week' ever come?! Or is this how I lose my phone to the dark abyss that is Telkom Claims. I have asked for an escalation on this matter and it seems that also doesn't make a difference? what device are you under the impression I have been using over the past 2 months?? May you please release my phone to me urgently?! I am tired of following up on what belongs to me.
