StubHub Refund Call Campaign

I need 20-30 people to call to Stubhub together (US number) and promote my use case. 5-6 hours a day to call them and ask for solution. I’m a seller there and they cancelled a sale I did and fined me (Budget: $30 - $250 USD, Jobs: Call Center, Customer Experience, Customer Service, Customer Support, English Tutoring, Lead Generation, Phone Support, Sales, Telemarketing, VoIP)
