It's a definitely no no. Blackmailers that's what they are.
Just recently booked them for a wedding in jaipur and they ruined it to the core. They keep asking you for advance and more and more money to get things done. They insist on settling the entire amount on the wedding day before completion or they'll switch off power. I did all. I gave them money and settled account before hand, still the power was lost due to their negligence. They installed generator of far lower value then needed and power went of mid function. Even other services guaranteed and shown was not upto the mark. Stage was broken and no coordination whatsoever. If you are looking for an event planner don't go with them or if you must be careful.

P. S. They do with different names.
Royal Heritage holidays is also their company
