RattanWarehouse review: Glass delivered smashed

I ordered a piece of furniture in April, but the glass arrived smashed. I called straight away and was told someone would be in touch soon to arrange a replacement.

Since then, I have been promised on four separate occasions by Lewis that the replacement glass would be sent out. We are now in August and I still have not received it.

To make matters worse, my emails are now going unanswered.

Has anyone experienced something similar or knows who I can take this complaint further to? Any advice would be greatly appreciated, as I feel I've been more than patient over the last four months.
