Indeed I did have a very similar problem last year. I had a Laptop that was to be returned to Tiny for repair, unfortunately I returned it the day before Tiny went into administration!! After 2 weeks of them reassuring me that it was still being dealt with and would be returned to me on time they changed their story and said that it was never received. I too had purchased the laptop using a buy now pay in 6 months option, and after months of arguments it was pointed out to me by a member of this forum that the credit company are legally bound to sort out matters such as this. As long as you have some sort of proof that the package was sent then you should have no problem, contact your credit company and explain the situation. I did exactly this and within 2 weeks had a nice new laptop at my front door.
