Ramothello & Tsotetsi Incorporated ************!!

I recently received an sms and an email from Ramothello & Tsotetsi Incorporated threatening me with a letter of demand on my Woolworths Visa Credit Card. This account was SETTLED and CLOSED IN 2012, now these *****/*********** legal collection agency want to get money out of me again. Firstly, its past its subscription date which i was informed by a legal representative and they legally cannot obtain money from me. I find this totally unacceptable on behalf of Woolworths as their legal representative. Since 2012 i have changed my contact no. and email address so how does this company get my contact details..?<br> I have proof of payment for the settlement of my account and i blame Woolworths Visa accounts department for not doing their job properly.
