EC loans harrasment calls and ******* deduction of money

Be carefull people.. Iam sick and tired of EC Loans telemarketers phoning me sometimes 15 times a day...i phoned their offices this week and complained and asked to be taken off their data base, but it still has not stopped,i dont know where they got my details, they even deducted money from my account which is ******* because i dont have any loans and i did not sign up for this...i have proof of all the calls and the money that was deducted off my account...they harrass you everyday, the whole day, week in and week out, even after ive spoken to the telemarketers and phoned their head office, gave them my details and still it wont stop, the numbers they call on can not receive return calls and usually says the number does not exist and every time they call its a different number, so you can block the number as much as you want
