Gomechanic — Company not initiating refund and stalling

On June 30 I booked a service in GoMechanic from Hyderabad but I received a call from Chattisgarh mechanic but not a mechanic from Hyderabad. Too much time later a Hyderabad shed was assigned and those irresponsible people never called me. I myself has to call them and they said that they can’t provide me with the service. I paid through walnut369 pay later service (and paid first emi already for mandate registration) but cancelled the order the same day. GoMechanic did not initiate a refund and walnut369 billed me for second emi. I had to keep initiating chat support of GoMechanic for refund and they tell that they have escalated the issue and I would receive a refund. But they kept my order was work in progress and initiated only Rs 2069 as a refund when I paid Rs 5196 through walnut369. Even on July 19 the status hasn’t changed and I still haven’t received any refund. They keep stalling me and ask for 24-48 hours of time each time I contact GoMechanic.
