Debited my account twice in December, different amount and without a reason, my issue is not resolved since December

Debited my account twice in December, different amount and without a reason, my issue is not resolved since December. now I received a message that I'm owing them while they are owing me. useless consultants and team leaders, never take clients seriously and they don't do follow-ups with clients. I regret signing a contract with this company and I will never recommend this company to anyone...
