Don't get adumo cart machine

I regret ever signing with Adumo. The card machine is unreliable, and now I’m stuck in a 2-year contract that I cannot cancel. Even though I am not using the machine, they are still charging me monthly rental fees and even added a R550 penalty. This feels unfair and like a trap for small businesses. The support team does not help, and they only push for more payments. I would not recommend Adumo to anyone looking for a reliable card machine or fair business practices.
