URGENT: Refund Not Received

On 27th August, Dell confirmed the courier has my return.

On 29th August, I'd received a credit memo via email.

On 8th September, I advised Dell my refund had not been received and was advised by Dell it may take up until 12th September to be received.

On 15th September, I advised Dell my refund still hasn't been received but was auto-replied staying my service request had been closed (prematurely).

This is abhorrent customer service, can someone please look into this immediately.
