Stick to a reputable registrar like... (Score 1)

Well I do not think you can do much about your lost domains. You can only learn a good lesson and stick with a reputable company. I use BulkRegister.com for the very beginning of the company and while their pricing is slightly higher, the company is extremely credible. IMHO, they will not refund anything no matter what you do. Do you know why? Because they are a scum and they do not care about their business, long term relationship with customers!
