Refund on bad services.

I purchased a meal costing R358,90 via Ubereasts on the 17th of November. The meal arrived and it was quarter of the portion which it was supposed to be. I immediately contacted Ubereats and they responded to say they have refunded me R204,00. This refund only shows on their App but has never reflected on my account. When I make a follow up, they responded saying they can’t help me because it has been more than 48 hours. This is dishonesty as they claimed to have refunded me when they didn’t. I will not recommend their services to anyone.
