Priority International — no response to emails and calls for more than a week now.

Address:

Andgeri, Mumbai City, Maharashtra

I am member of priority international for more than 5 years now i have used the service couple of times in 2015 and 16 but now i am trying to use it again this year they simply not picking up the phone i have been trying for last one week with multiple emails and calls to multiple numbers but still of no use no one is responding or replying.
I've heard of a cheating case registered against them sometime this year. Now i am little worried if that rumour is true as nobody is responding not even the person with whom i registered and had contact in the past years.
Please suggest how should i take this further as i have paid all the registration amount of one lakh rupees to them 5 years ago.
Thanks.
