Simple change of account holder and your service gets suspended till Octotel come back from festive season???

Signed up with one of Octotels ISP's and all I needed to do was change over from one account holder to another and because of Octotels freeze period 21st December 2018-7 January 2019 I have No service untill they decide to come back to work.??? How can internet service providers or telecommunications providers have no skeleton staff over the festive period???
