GoAir — regarding correct in name

I have reserved ticket for 22 june 2018 with pnr no. R4t59c from chennai to pune
By mistake at the time of booking the name typed as mr. P ganesh pandey but i want to correct this name as p. Ganeshpandi. Plz correct according to my request. I have panic due this mistake. I also contacted to customer care but i have got very worst treatment. Its very small thing but no one from your organization give me good treatment. It's very shameful. Also they told me to cancel reservation. For only small correction why i cancel the ticket. It's not good policy.
So it's kind request plz give correction in the name
