Still haven't received my money?

I ordered a set of pots early in September. The website stated I would wait between 5-7 working days for delivery. On day 7 I receive an email stating that the supplier is out of stock and I would need to wait a further 14 days for delivery. Again on the day that delivery should have happened, I receive an email to state that their third party supplier was unable to provide the pots. I then queried why they continue to advertise the same set on the website if they know it is out of stock - no real answer to that. The consultant promised to check and see if she could source this elsewhere for me or alternatively they would refund me in full.... Needless to say more than two weeks later I have not received a follow up call or my refund... This is totally unacceptable. I want my money back so that I can spend it at a real online vendor like AMAZON Contact me to make arrangements or I will lay a case of theft against you
