Swiggy — refund - already been more than 2 weeks

On the 7th of june i placed an order through swiggy (Order no - [protected]) to have 4 food items (Total amount paid - rs. 961) delivered from freshmenu (Malad). 30-35 mins into placing my order i recieve a call from the assigned delivery man that 3/4 items that i ordered was not available, after that i receive a phone call from swiggy's customer care telling me that i will be refunded for the remaining 3 items. The total amount that needs to be refunded to my account is rs. 798, it has been more than 2 weeks and after following up with them 4 times alreday i feel ridiculous to follow up once again for my own money. I've been given false assurance 4 times already and i do not believe going back to them is going to solve my problem.
