They owe me money for 6 weeks

I purchased my Samsung S24+ via samsung I sent my phone to Regenerate on the 22nd of Feb. This is after waiting over two weeks for them to get there ducks in a row to arrange the collection. I have already been waiting 6 weeks for the payment for my phone. On 8 March, I was promised payment on the 28th March, now one day before the promised date, you go back on your word. Saying there is delays with no prospective dates on when to recieve payment. Extremely embarassing for Samsung to deal with this company and subject their customers through this flawed drawn out process.
