Natasha construction pvt. Ltd. Is the worst contactor I have ever seen. Once u give them a contact , the work will never be completed in the stipulated timeline. Their charges are also very high. The materials they used are also of a little bit sub standard. Once you give them the advance money or full pay the amoount you will be harassed. Neither they will complete the work nor they will return your money. When you will sue them the case will continue for long time. You can not do amything against them
