Talktalk ACCIDENTALLY cancelled my fibre package. Now I got to wait till after 5th jan with 4 kids

1) i had talktalk fibre broadband package and went live without an engineer having to come  out and was earlier than initially stated by a day or two. HOWEVER talktalk accidentally cancelled my account sending me an email saying that "WERE SORRY YOU'RE LEAVING US " after a third party cancellation notice ... this was news to me .... so we had the Internet going for a few weeks however not noticing that last week as was working away from home ... finally got them to have to renew the account having to start the whole process again rather than just apologise for the mistake and correcting it back to live account...now I'm at home with 4 kids and all the 4 Tvs, 4 Xbox all phones and tablets all 8 alexa devices and smart switches , door bell , and everything a family needs is not working ... CHRISTMAS IS FRIDAY AND NON OF THEIR PRESENTS WILL WORK..... as got to wait in total 3 weeks from the 14th of December to the 5th of January for an engineer appointment (THAT I DIDNT NEED LAST TIME SO WHATS CHANGED) AND A ROUTER delivered for the 4th ...we still have the 8 week old router plugged in so don't need that either ... we were connected on before ... WHY THE DELAY AND THE ABSOLUTE HORROR OF PANIC AND ANXIETY your giving me about Christmas period and how terrible you are making it for our children , through your mistakes, we can't even go round families houses to fill any awfully boring days as were not allowed with the covid restrictions....HEEEELLLP ME
