Due to certain suspicious or unrecognized activities from your account, PayPal imposes some restrictions on your account after which you are unable to make any further transactions. In case your account is facing such kind of limitations, it doesn't always mean that any unauthorized or illegal activity is recorded from it. Sometimes, PayPal Customer Service does so in order to help provide the much-needed protection to both parties.
In case you are unaware of the account limitation being imposed on your Business account, then you must know that it is a kind of restriction that puts a stop to any future activity from your account until that restriction is lifted off. So, you must try your hands at getting this limitation off from your account, be it a personal or business account.
