Poor customer service - inconvenient!

My order was canceled by the store. Instead of refunding my voucher, the voucher disappears. It took a day for Mr. Delivery's customer service to get back to me with a “Here’s a voucher to make up for the inconvenience”. It was the same value as the voucher that should have been automatically credited to my account… does NOT make up for the inconvenience caused.

I tried purchasing a celebration meal for my staff today and when entering the voucher, it doesn’t go through. Very unhappy with the quality of customer service received.
