MDC Recovery and On Air TV

I have written a previous review regarding MDC emailing and smsing me with threatening messages. I have no idea who this company is nor On Air that they are collecting on behalf. I am stunned that they not only have my contact details but my ID number too. I have contacted them several times to stop contacting me and removing their fraudulent records on my name. They blatantly ignore me and persistently continue to harass me. They are major fraudsters!
