HappyEasyGo — cancelling my cancel ticket again and again

My flight was cancelled due to covid-19 which was on 5/04/2020.
I initiated for full refund got full refund mail from airlines and when i cancelling ticket from happyeasygo they cancelling my cancel ticket again again and i can not got revert my money without cancelling tickets from happyeasygo.
Very irresponsible and unprofessional behaviour.
