Ask around for quotes on delivering a fridge comparable to the one bb was supposed to deliver, within the same timeframe. Keep documentation, which can include just your notes on who you called and when. Presumably you won't get many quotes, that's fine. Do it until you get one, and execute it. Later, but not too much later, sue BB in small claims for the difference between the price they charged and what you ended up paying. It doesn't hurt to ask for some compensation for your time, though you're less likely to get that. The point is, you are most likely entitled to be made whole for any increased expense you incurred to get a fridge on your required timeframe, as a result of BB's breach of contract (yes, you had a contract with them - you have a contract every single time you purchase something, whether it's written or no).
