I got a Mag 254 and just purchased a rocket, following a step by step instructions, I got to # 9 and reboot. after the reboot a message comes up : Your STB is blocked Call the Provider. now I have Time Warner Cable / now Spectrum. is that possible for them to block my box ? or what do I do...

I paid for a new rocket on Friday the 24th. Today is Monday the 27th and I still don't have the rocket. they did take the money out of my account, this not use to be like this! Any ideas what should I do????
