Worst Claim process

I have had the worst experience with Discovery in claiming for my cellphone. Once claim was processed, discovery advised that they have paid the replacement amount and I have confirmed with them on a number of calls generated by myself that the funds have not been received. This started on the 11th of April and to date the money has not cleared in my account. I further requested that they share POP so the payment can be traced and they have failed to do so. I keep calling and holding for almost 30mins daily to follow up on same and issue is still not resolved rather than being told the same thing everyday (we have paid). Yesterday i escalated this issue to their Team Leader who has not even bothered to respond to my mail. I need this resolved immediately as I pay my premiums monthly and would appreciate if they kept their end of the agreement.
