Bad Service from the Market place and Leroy customer care

Bought lenny floating unit via Payflex during Easter Holidays. A unit that shown online while it was not in stock. The following week I was then told the unit is not available after a week of waiting for it to be delivered. I than asked for a refund and I was told it will take 24/72 hours to be finalised, it has been more than 4days now and whenever I call the customer service they always put me on hold and never come back to me. This is really frustrating as I am typing this I’m still waiting
