unauthorized charges on my bank account

I have had unauthorized charges on my checking account for past 2 months in the amounts of $1.00 on 2/21/2019 and $19.95 on 3/29/2019. I did not recognize the name Schrug on my statement, but was unable to see a phone number to contact, and I thought I would contact the bank, however it slipped my mind, and now I want to report it. I have not yet contacted my bank, but will do so on the next possible opportunity. I did not authorize any charges to Schrug.com, nor have I ever heard of a company by that name. I realize that a lot of times an online purchase will appear differently than expected, but there is no reason why or that I did in fact do any business with this company. I do not know where or how they accessed my information, but I have recently purchased a new computer from a Rent to Own store, and it may perhaps be due to that. I don't know, nor can I find any other reason why or how my information could be compromised. Thank you for allowing me to report this.
