they say I owe them for doing online quotation

Hello peter<br> Sometime ago I did an online quotation with Loan Match,as they have been inviting me with sms to apply fo their loan.i just did a quotation and that was it.i hve been getting calls from this people sine that online quote,harrasing me and forcing me to take the loan with their client,which I didn't agree to.i stopped answering private calls because most the times I was then calling,they have been deducting my account and every time I will go to my bank to reverse the transaction but they don't stop.yesterday and today I received an email from esterhuyze attorney threatening me about legal action,saying I owe their client..what the ****?loan match and ur attorney please get this I owe you nothing and stop debiting my account
