Unauthoried debit orders

I recently discovered four charges on my account, that when Googled, turned out to be from your company. These charges are: Somu Em, Ispb Em, Phob Em, and Milc Em. Upon browsing HelloPeter it became apparent that I am not the only complainant against these charges. I have never signed up for any of these services. Nor do I even know what they're for. These charges have been billing my account from as far as 2013! I want these charges rescinded immediately, and the monies debited from my account to be returned with immediate effect.
