Poor service delivery and call centre.

I received my S20 ultra at the end of March. I placed my application for my free buds that come with the device. Its December and I still don't have them. Every time I call the support centre and give them my CITD number I get the same response. You're request has not been sent for delivery, there was a delay due to Covid restrictions. It will be processed within 5 working days. Ithen ask to speak to the manager, who has not once been available for my call, and am told that the manager will call me back. To date I have received exactly 0 calls... Naturally the delivery doesn't happen and so we start the process again. I'm at the point of wanting to return every Samsung device that I own and wash my hands of this company.
