Shared my bank details to another institution ********ly

You have given NUDEBT my banking details to debit my account and sent me treats on sms.I am unemployed and what you have done is ******** because I had a mandate with you not NUDEBT.I will pay then I find employment but my issue is that they run 2 debits at anytime and I receive grant for my child to take care of her needs but because of the unpaid fees constantly on my account I cannot take care of my childs things.I will report to xonsumer protection as its against the law to share my banking details with another institution to take money from my account.I did not give consent for NUDEBT to debit my account.
