GoAir — not a single customer service is working

I have booked a ticket from new delhi to bagdogra on 27.03.19, i have tried to book the ticket from the smartbuyhdfc, i had a query regarding surname issue. I contacted the customer service of smartbuy hdfc and they suggested that i should talk to the airline directly, i was in the middle of the booking i tried 50 times to contact all the numbers given in the airline website but none of them were working. And also not a single email id was given for the customer service.
Where should people talk in the time of emergency or any changes?
Very bad airline. I will never book a ticket in this airline and nor i suggest to anyone.[protected] / +[protected],[protected]. All these numbers are bakwas and irrelevant
