Hello Sarthak12,
Welcome to the community!
Had you recently signed up for pre-authorised payments? MACC stands for Monthly Automatic Credit Card (see here).
You should note, though, these forums are community-driven and are not intended as a venue for customer support. If you wish to discuss your matter, you would need to contact customer service. In addition, they can also be contacted via Live Chat, Facebook, or Twitter. Those methods can be accessed via the contact page posted above.
Hope this helps 😀
Cheers
