The contractor does not deliver the renovation work as agreed. What to do?

Dear sir/madam,

I hired a contractor to do my villa renovation in Meadows, Dubai in April 2022. The contractor's team is not technically sound, and everything has to be worked on a minimum of 2-3 times to make it right.

There are structural defects in the workmanship of his team; for instance, the concrete pillar they made to support the structure was titled. His entire on-site team is illiterate (meaning they can't read and write in English) including the project manager.

My husband and I have been doing project management to keep things going for the past 4 months. Based on our contract, he has got more work within the Meadows community, and he pays no attention to our work now.

Things have gone from bad to worse. The whole process has been delayed by more than 4 months. We are sick and tired of it.

By the way, the contract that both parties signed is loosely written.

Kindly advise what legal recourse we have in this case.

Many thanks!
