Terrible customer service - no stars

Terrible customer service. Upgraded a contract. Billed me for an uncapped data plan and gave me a 100G data plan instead. Now trying to fix the problem. No email option only to call. I get a different person every time. They wont cancel the contract until they collect the router but they wont book collection for it. Each time I speak with them I am given a different time line from 3 days to they meant 7 to 14. This has already been 3 weeks, almost a month now. If I could give no stars, I would do that.
