Being harassed daily by Cartrack.

I recently got retrenched from my employer and with that I have not been able to pay my installment of R142, which Catrack is now hounding and harassing me for. I have given them telephonic notice which I believe is 20 working days and this notice period expires around the 6th of June according to a conversation I had with one of the call center agents at Cartrack. Yet, I am still being phoned, sms'd, emailed and WhatsApp'd numerous times and everytime I have to explain that I am unemployed and don't have the money. I'm in the unfortunate situation whereby my husband too is unemployed. We've had to cancel a few of our policies, etc. Just so we can be able to live and keep food on the table.

Cartrack will yet still insist on phoning 3 or 4 times a day. And what's more is, if they can't get hold of me they try phoning my husband. We happen to be married anti-nuptially so my husband has nothing to do with my affairs.

I have reached the stage that I start getting heart palpitations everytime Cartrack phones, and each phone call leaves me feeling sick. Cartrack is not the only company that I owe money too. Your amount of R142 is but a drop in the ocean of what I owe other companies, yet the other companies are a lot more understanding and don't harass me like Cartrack does. I'm sure the rand value of all the phone calls and emails Cartrack has made and wasted equates to far more than what I owe them. If I'm being harassed for this amount, I'd hate to know what would happen if i owed them much more. I really feel harassed and I want this to stop. Cartrack is affecting my health and NOT in a good way. What do I need to do for this to stop?
