Rain demanding payment to a non client.

I canceled my rain internet service in 2019 or so but for some strange reason now October 2023 I am receiving sms's and emails of letters of demand that I owe payment. I am emailed rain support and some company they use aclled nudebt to inform them that I am not a client of Rain so I can't be owing. I have not used their services since I canceled years ago. Rain needs to check this out and sort it in case maybe someone used my ID *****ulently. I don't owe.
