Paramount Group — not getting response from paramount representatives

After many followup over emails/phones i'm not getting response from paramount representatives for my unit p-1729. I received possession letter, i was looking for some clarification on which i'm not getting any response. I dropped 1st email on 22nd dec. Till now dropped around 15-16 email but no response on the same. I talked to paramount cc multiple times but still no response which causing delay in payment and possession. I talked to aradhana and gurpreet. Always getting response that we will check and let you know. Since more than 1 month i'm just waiting for response on my concerns, so i can pay final amount but in lack of response not able to pay the same.

Way the executive handling customer really disappointed and not very effective.
