Nimble Group again

This company is a ****. Do not trust them at all as I don't believe they do any legal debt collections, only **** ones. About 2 weeks ago I posted about them contacting me about a Supersonic Account for some other person. I have 2 phones and on my second phone I keep getting messages about a Nashua Mobile account. I usually just delete these messages but now have seen that it is the same **** group. I last had a Nashua Mobile account over 20 years ago and closed it when Nashua Mobile stopped doing mobile transactions at that stage. It was never in arrears. Now since about 6 months ago I keep getting these messages about my "Nashua Mobile" account. How can these **** companies get away with this? I am definitely going to follow this up legally if they continue this with me and will report to consumer council
