Individual applicant haven't been contacted by exam centre for exams help!

I had an exam centre before covid to do my alevels but due to covid we were strongly advised to withdraw out application for the time being incase exams would not take place.. But we would be allowed to re-enter into the exams when we knew exams would be taking place.
My exam time table is out but I haven't been contacted by my exam centre at all.
I don't know what to do
Should I email them to ask how to re-enroll or what the next steps are.
If anyone has been in the same situation would rlly appreciate some advice.
