[BC] Shaw screwing me over

So I switched from Shaw to another cable internet provider which is reusing Shaw's cable infrastructure. Naturally, I close my account with Shaw so I don't pay two providers for one service. While there was an overlap when both providers were being paid, my service worked and I was getting my IP from the new provider. There was a one month overlap due to Shaw needing a 30 day notice. So Shaw came last Tuesday to disconnect my service. Do they not even check if a customer is still a cable internet subscriber with another provider who is leasing some of Shaw's cable infrastructure? I was told there would be a Shaw tech (by my new provider) coming by Sunday morning to reconnect me. Noone came. I followed up with my new provider and they reopen a ticket with Shaw. No new date is set for a Shaw tech to drop by. I went as far as calling Shaw directly, but they said as my account is closed, they can't do anything for me. I could however reopen my account directly with Shaw and they can send a tech within a day. But in my scenario, I have to deal directly with my new provider and have them chase down Shaw. Shaw is effectively being a dick and making life difficult for 3rd party resellers and their clients.
