Currys complaint: Replacement Machine

A Washerdryer we had ordered in December 2020 broke down in June 2021. A contractor attended and advised that parts would need to be ordered. After a week, having not heard any news, I contacted CurrysPC World who informed me that parts had been ordered. Again, having not heard anything for a wee- 10 days, called again to be told that it would be September (6 Weeks away) before the parts came in. This advisor then offered to write off the machine as it was a long time to wait for the the parts.
Since that call, I have been on the phone every week,- sometimes 3 times a week – trying to organise a new machine, being told it was out of stock, ordering an alternative , again one call said it was ordered, the next call said it hadn’t been ordered(I was waiting for notification of a code in order to be able to arrange delivery). Then it had again – still no notification of delivery date which leads me to the final call where I was told that this machine was now out of stock until 29th September. A 3 year care plan was purchased along with the machine, however, due to the new replacement having a standard 10 year warranty, I cancelled this. I did receive a pro rata refund, however, as the machine had a standard 1 year warranty, I feel that a full refund for the care plan was justified.
To add insult to injury, when this order was placed in December 2020, I paid for our old machine to be removed and recycled. This was left in the corridor outside my flat after not being removed, I had to pay a third party company in order to remove it.
