Important service quality

Recently  I found a decoration company to decorate my new house , after we signed contract and started to decorate, I felt some thing was wrong during decoration process , the  decoration company service is not satisfied by me ,install water and electric ,install floor tiles ....... too slow for the.ir schedule , and decoration quality not well, some detail place they didnot consider, cheap jerseys, need me to remind them, another  they always said they didnot get high profit ,that's to say I need to accept their poor quality. I almost fall up for these bad  things. this is not meet my original expection. so if I have chance to change this , I will select more expect team to decorate.
