No Delivery - delay on refund

I receive a notification from my bank that they money has gone off, and then 30minutes before they were meant to arrive I received an email notifying me that they wont make it; so I've wasted a Saturday waiting for them. After which Im informed they will now come Monday; to accommodate this I needed to get my domestic in an additional day, and obviously pay for this day. Guess what, they just don't rock up again. Following this I requested a refund and cancelation through various attempts from their call center, this took another 2 days for them acknowledge the return and Im still waiting for the refund to be issues. To top it all off, when they finally got back to me they informed me I will have to wait 3-5 working days for the refund. This is degusting! Not only have the cost me actual money and time, now they are slow in their process and tells me I now have to wait another week for them to give me my money back.
