Manager Still not signing off Refund.

I have recently purchased a vehicle from the imperial select George this process was GREAT David and Lezele was awesome. Friday on the 15th December 2017 David informed me that they have to refund me some money back to me. I fill in all the information their refund form and David informs me that it requires sign off from the Manager this is Friday Morning. Monday I emailed David and he directs me to a lady called Tori that works the accounts. She tells me that she is waiting for her manager to sign off on the Refund that again was Monday morning. it is now day 3 and still no sign off from the manager.

Can someone please get hold of the MAnager at that branch or try and find him because it seems like none of them can find their manager to sign off.
