Hello,

1) Their labour problem is not your concern. They have to deliver as per the contract if you had drawn up one. As time is the essence and you are not getting the work completed by the service provider you can seek compensation and survival performance of the contract.

2) Get a legal notice issued to them demanding immediate completion of work and delivery and seek compensation in the alterative. Mention in the notice about the exorbitant amount being charged by them and seek adjustment in the bill or compensation.

3) You can file a consumer complaint before the Consumer Redressal Forum depending on the response of the erring interior designers.

Then I cross checked in the market. I found they are charging money on everything on which they can put there hands on. It's making a difference of at least 10 to 20% which I would have got from the market. And they are charging 10% of the cost which they charge for there services. I'm feeling cheated. What can I do?

You may go by the conditions of agreement entered with the owner and if found to be in violation then you may orally inform him about it, if he is not listening to oral request, you may send a legal notice about it and ask him to refund the excess charged from you and close the mater with immediate forthwith.

Ifg there is no agreement between you both then you may inform him about it in writing and seek the releif and refund the losses you suffered due to their cheating act.

After this you can either drag them to consumer forum or to the civil court seeking remedy and relief.

When will I get my answer? Sorry but running out of patience.

Hope the answers are convincing, if not you may revert with more proper details for a more proper opinion.
