Marrow — My marrow account got suspended due to 2 devices login

I purchased marrow subscription 3 days back and yesterday my account got suspended due to 2 devices login which are mine
I haven't played a video yet I mailed the to legal support of marrow and replied you make them a new plan then only your account will be unblocked
How can I purchase new plan for myself again
I mailed the same to them but they haven't replied yet
Please help me get my account back
