Account suspended,but they want R880 from me

On december 31st I received an sms that due to non-payment tracker is forced to suspend my account.Tracker emails me every month regarding my invoices.Since January 2015 I have not received any email,sms or call from tracker,so my assumption is that my account is suspended.Today I am called to be told they want the money for the past 3 months,which if I should have called to say my car has been ******,they would not have assisted me as Lenon answered my question regarding that via phone.Why should I pay for months that I was not covered for?Apparently the system shows that my account is active,if so why did I not receive 3 months worth of invoices?It is not an error not to be sent statements on my account,it is because my account is suspended.When a person is in arrears still statements needs to be issued if the service is still up and running.<br> The person who called me told me I would have been assisted should my car be ******/hijacked,Lenon says I wouldn't have been covered,so whats the real story here Tracker??
