Legal Action

I am sick and tired of getting sms's from the legal department of Vodacom. I have tried to resolve this problem by sending a email to the department that is responsible for the debt collections whose email address I got from the customer care centre in Midrand. They sent me a ref # and I quote \We endeavor to solve all email queries within 24 hours"unquote. It has been 3 days now and I have heard nothing from them except for the fact that I receive sms's every day telling me that legal action will be taken against me if I don't respond. I CAN ONLY DO SO MUCH!!!! If these sms's persist I will be taking legal action against them for harassment."""
