Proceeding with Summons??!!

I just received an sms from a Ronell from [URL Removed] stating that legal action will be taken against me if i do not pay my arrear account. They have already blacklisted me on the Credit Bureau and have handed me over to their attorneys, Whalley & VD Lith. What?? I haven't been with Spectramed since 2012 and NEVER received this account?? No communication from them just a warning for a Summons? I am disgusted with Spectramed, good riddance! Can someone please contact me URGENTLY then? My reference in your sms is SPE012481/VENTER.
