Amazon Flex stopped paying me

Amazon Flex
Amazon Flex is basically an app which you install on your mobile phone. Along with the app, goes this contract, the Amazon Flex delivery contract. AMAZON FLEX INDEPENDENT CONTRACTOR TERMS OF SERVICE
You’re not employed by Amazon as a Flex driver, but you’re self employed providing a delivery service on Amazon’s behalf.
All your packages are provided by the company, and you have to go to the depot to pick them up.
In the case it was the Northampton Depot on Saxon Ave, DNN1.
This is where I’d go for each delivery block. At the end of each week on a Wednesday, you’d be paid the amount owing for the previous 7 days, into your bank account.
