Worst service and experience

I went into the Woodmead store the 29th March for a TV. They advised they don't have stock, but I should order online as the other stores have stock and will deliver.

I placed the order and process the payment on the 31st March. They call me on the 7th April to tell me they don't have any stock and will refund me. Refunds take 7-14 days this is absolutely unacceptable. They should never have taken my payment if there is no stock. Also a refund should not take 7-14 days when they cancel the order.

I have been online since and I see the TV I ordered still shows available and can still be purchased.

However they are telling me there is no stock and I must no wait even longer for a refund. It's the worst service I have ever received and they have absolutely no interest in assisting the customers.
