sub standard product and can't backup waranty

I installed my floors 2 years ago and had them out 4 times to come redo it due to floors lifting and splitting apart. They even had to use product I had left and could not finish the last time fixing the floor because they do not carry stock of the floor I bought any more. Don't give warenties you can't keep it has been 4 months since they redid my floor and guess wat started splitting again but yea my problem now cause my 2 years are over. No one gets back to u they don't replace what they use and they sell a **** product
