What is "OMO MK"?

OMO is a service that helps you manage your subscriptions and bills easily. They offer a simple way to keep track of your payments, so you won't miss any due dates. If you've seen a charge from them, it might be for a subscription you signed up for or a bill they handle on your behalf.

OMO: This typically stands for "Open Market Operations," which is a term that can refer to actions taken by a bank or financial institution to manage the money supply. However, in a transaction context, it may not need detailed consumer explanation.
MK: This usually indicates the merchant or company initials, possibly related to a specific brand or retail store where the transaction occurred.

Verify With Receipt

The best way to tell if this charge is fraudulent is to find the receipt. You may have an electronic copy of the receipt, which Chargeback can help you find by searching your email accounts.

Chargeback helps you identify unwanted subscriptions and charges, and help you fight them to get your money back.

If I see this charge, what should I do?

If you see this charge and aren’t expecting it, you have various options.

First, try to contact the omo.mk via one of the support methods we listed below and inquire about the charge. See if they will refund it and cancel any associated subscriptions you might have.

If the omo.mk refused to issue a refund or you cannot get in touch with the company, call your bank or financial institution and open a credit card dispute. Record screenshot evidence from your prior conversations with omo.mk, and use that to open your credit card dispute. Tell your bank or credit card issuer that you do not recognize the charge and do not recall signing up for the service.

If this sounds like too much of a hassle, you can have Chargeback do it for you.
