The customer service at Mastermind Abacus Indore is excellent. They are always prompt in responding to queries and resolving issues. I've been using their services for over a year now and I'm completely satisfied with the results. The abacus training program has greatly improved my child's mental arithmetic skills. I would highly recommend Mastermind Abacus Indore to anyone looking for quality abacus training.
