Spice Jet Airlines — customer care numbers not accessible nor web page functional

Address:

202 Carleston Classic, No 3,Carleston Rd.Cooke Town, Bangalore, Karnataka, 560005

I had booked a Spice Jet flight from Hyderabad to Bangalore for the 16th of March'19 (PNR No. HD5M6N).
this flight has been cancelled and I received a message stating the same along with a link (http://changes.spicejet.com) and phone numbers[protected]/[protected]). This was given in order to claim a full refund.
After several attempts on the link, I kept getting a message that there was a problem and I should try later. I have been trying this from yesterday and today (14th March'19)
The customer care no.([protected]) is of no help as it always says "your call cannot be completed due to congestion, try again later). The alternate no.([protected]) does not even connect. i do not want a situation whereby because I could not cancel my ticket online, the company uses it as an excuse not to give me a full refund

I wish to be notified by way of e-mail ( [protected]@yahoo.com) on the status of my refund.
thank you.
