Purchsed stock, not supplied, refund promised but never paid

I purchased a number of used printers from Innovate Group in February 2019. I ordered these and paid in full as requested. my couriers arrived to collect the stock and was told that it was not ready, over a month of being told that they would deliver or we could collect I was eventuallly offerred a refund. I accepted the offer of a refund. To date, over 2 yearslater, despite numerous promises by Innovate and efforts for me to get my refund, I have still not received my money. Be very wary of Innovate Group.
