Hi, About a month ago I started getting odd texts from a company called CRS, the text had a ref. number and a message saying please contact us. These texts carried on over the next few weeks but started to become more threatening, i.e. court action. I googled the telephone number and it brought up CRS ltd a DCA. As I had no idea what the debit was referring to I ignored the texts thinking it was some type of [problem]. Two weeks ago I received a letter from CRS ltd asking them to contact them regarding a debit of £136 with regards the ref number at the top of the letter. As the letter didn't state who the debit was owed to or for what I sent them a letter on the 13/11/12 based on the template from another website to tell them I had no knowledge of the debit and to not contact me any more unless they could provide evidence for the debit in question. I sent this by recorded delivery ( just checked the track and trace on the Royal Mail website and it says come back later). This morning I received a text from CRS saying they are passing my account on to HL LEGAL and to stop this call Sarah at CRS. If I do owe somebody money then I will sort it out, but I refuse to pay somebody I don't know for a debit I'm not aware of. And can't believe that they don't state on the letter where the debit has come from. I hope somebody on here can advise me, did I do the right thing with the letter I sent to them? Can they start legal proceedings against me? And do I have the right to know what the debit is for?
