Abdicating responsibility, leaving me hanging with financial loss

I purchased a product from First Group which is a subsidiary of First Tech I believe. I purchased a product that failed under warranty. It’s been 2 months and I have neither my repaired product or a replacement. They are making their problem mine and only want to give me a refund. Now, does one want to invest in this company as your partner if warranties mean nothing? If after only 2 years they cannot acquire a replacement unit? Is this what you expect from a tech company? I simply would not recommended dealing with them if they cannot ensure my business runs smoothly.
