While I moved in Sep'20 they told the rent would be 9k for a private room including electricity bill up to 500 and water charges of 200. Same was mentioned into the rental agreement. On 1st they generate a rent invoice which is to be paid till 5th or there will be late fee charged 100 per day. On 5th they generate a separate invoice for utility bills which they call it for electricity and water usage in which they charge for common amenities like hot water, kitchen and common areas usage and it comes to be around 3k. The have not given any clarification over it and did not say anything when new tenant moves in so there's nothing in written about these charges. Basically its their wish they can charge any amount and no proper customer support is there regarding it. If someone doesn't pays this unnecessary amount they are deducting from the deposit.
Also there services are worst mostly no drinking water is there, hot water doesn't comes, plus no water in washroom. Please help me to get my money back from this fraud company.
