More disappointment from Mr Price Home

I am so disappointed in the service or rather lack of services from Mr Price Home. On 23 February I bought myself a lovely cupboard, and was excitedly waiting for delivery. The couriers made an appointment to delivery, the day came and went, they then made a second appointment, which came and went with no delivery. I then called customer service, and the courier company arranged to deliver the next day, which also came and went. Once again I contacted customer service and told them to cancel and refund me, this was a week ago. I then contacted them yesterday, sent the message trail, and was told they’d come back to me - nothing. I then contacted them again this morning, was told the person dealing with it is only in at 10:30, I then asked for the email address for a supervisor or senior person, was told a manager would contact me - still waiting. Meanwhile on the tracking on the app shows that the cupboard has been delivered. Mr Price you have lost a loyal customer. I do not think that it is fair treatment of any customer. Can I have my money back now please? It is not fair to me as your former customer to be disadvantaged by an inefficient process or is it an untrained staff member, I leave that for you to decide.
