GoAir — cancellation of pnr e2967y

Am trying to reach goair helpline since 5 days. None of the numbers on their website are working. I have written multiple mails to their nodal officer too but have not received a single response. Pl help to cancel the pnr e2967y as senior citizens were travelling to delhi for religious visit. The trip is cancelled owing to coronavirus threat. They keep sending promotional mailers but are not competent enough to handle customer grievances
