Lyft

I first used Lyft because a friend recommended it, and while I was in San Diego, CA. I used his referral code, which promises a bonus credit to both parties.
I’m new to using app-​based taxi services. Out of curiosity, I asked my driver (in San Diego) what he thought about it. The first thing he said was, «You don’t make as much as they say you make.»
Fast forward 2 weeks, and I did not receive my credit. Not only that, but now they’re denying I can receive credit because I’m in Madison. I did my best explaining the situation with half a dozen emails to customer service, but despite the cheery attitude, I’m left empty-​handed.
***To their credit, Lyft support responded to me on Unilocal,and will honor the $ 20 code
