Harassment for 'outstanding' debt which doesn't exist

I've been receiving sms's from MBD Inc on several occasions in connection with a Virgin Mobile Contract. I did inform them not contact ,e as i was sequestrated and the debt needs to be written of as per court order,. I even forwarded a copy of the court order to them as proof. Today i received another sms fro them : Limited time offer! Call MBD INC. on *** for a 50% discount on your bought Virgin Mobile acc. Ref 0278 *** Ts&Cs. Which part do you not understand??? Please stop harassing me . Go look for Case 2016/19295, Judge Monama.
