Bolt refusing refund

2 September 2022 I took a ride with Bolt for 2km, with the estimated cost about R30. That same night I got a notification from my banking app that over R400 was charged for my ride. Since Bolt has no telephone number, I contacted my bank and stopped my card in the hope that it would cancel the transaction until I could contact Bolt, but the transaction went through regardless. The next day I contacted Bolt and found out that the driver never ended the trip. I was ensured a refund within 7-10 business days. More than a month has passed, with me contacting Bolt through their app constantly to no avail. I have been ensure that they have refunded me, but that has not happened at all. I have tried everything in my power to get through to Bolt regarding the refund. I have contacted them on social media, tried to reverse the transaction through my Bank and lodged an official complaint with the Consumer Goods and Services Ombud. More than a month later, and I am still waiting for my refund. Bolt is replying to my requests days later, clearly hoping that I will forget about the money and give up.
