Is it legal for a compny to debiit money from my bank account without notice?

No, it is generally not legal for a company to debit money from your bank account without your prior consent or notice. Most jurisdictions require companies to obtain authorization from the account holder before making any withdrawals. If a company does this without permission, you may have the right to dispute the charge and seek a refund. Always check the terms of service or agreements you have with the company to understand your rights.
