Four months to deliver some bedroom furniture only to find that the wrong bed was delivered and other items had arrived damaged in a number of places. When I requested a replacement, I was told that there were no delivery slots available in the next three months (at least - their system only showed 3 months in advance). Customer service responses are painfully slow and amount to a collective shrug of shoulders, never really looking to resolve the issue.
A month after reporting the issues, I'm still waiting for the collection and refund which means that I'm sleeping on the floor and I'm £1100 poorer as a result thanks to Marksies.
Avoid like the plague...
