Charged for renewal after service was cancelled

I received an e-mail on the 12th of Dec. 2014 asking if I wish to renew my service with Loan Detector SA at the end of Feb 2015. I responded the same day via e-mail to the address provided. Got NO response from them.<br> End of Feb 2015 I receive an sms requesting I fund my account with the required amount to renew my service I phoned their office number and spoke to a consultant stating that I cancelled my service I asked it not be renewed. She asked I send the email I sent which I did. Still no response from them. This morning I received an e-mail form their legal team saying I have been handed over for the amount and the legal fees. I phoned them again spoke to yet another consultant stating I will not pay a cent. He even confirmed that he could see when I sent my mail and everything and the service was supposed to be cancelled and he would refer this to his manager. Still waiting on the reply. This is the service you get from a company that sources loans for people? This is unacceptable and I will advise anyone DO NOT USE THEIR SERVICE.
