DMC and its ghost consultants

I have been paying them my account for quite some time. I informed them more than once in the recent month to freeze the debit order amount as I left the country and need to just get on my feet with the new job and will start paying again in about two months but will inform them once my new salary is sorted. They dont respond to mails. They told me over the phone that they will do it. Everytime I asked has it been done, its always "I cannot see it in your profile". After I came from an interview now i got notification saying DMC has dedcuted money from my account. So now what the hell is going on there? If i dont get closure within in this week i ll have to block them externally and take different measures. Its pathetic. A citizen is so cooperative but now im overpowered with incompetance. Are you guys uitgevriet for money or something instead of helping a citizen.
