XXXX   XXXX   called me in   XXXX   XXXX   XXXX     and told me i was eligible for supplies for my   XXXX   XXXX   every 6 months to include face mask hoses filters and humidifier.   i checked with my insurance benefits department and the y said yes   XXXX   is correct these items are covered.   Ordered items received items and   XXXX   XXXX   XXXX   XXXX   paid for items and sent me a statement staing i owed {$0.00} for all items.   A few months later  XXXX  sends me a statement for  XXXX  not sure of exact amount. I call there company and request an invoice to back up their statement. I never receive an invoice and no one ever calls me back.    Month later I  receive a statement from  XXXX . I request an invoice i never get an invoice ... i call  XXXX  and tell them about   XXXX   statement which shows i owe {$0.00}.   No one calls me back i do not receive any proof from them.   Next month i get statement from  XXXX . We do the same dance we get the same results.   a year later i get a notice from a debt collector about overdue account. i call them explain situation ask them to provide me an invoice or itemized bill from  XXXX  they do not .I send them copy of statement never hear from them again.   a year later i get a letter from a different collection agency. i call them ask them to provide an itemized bill from apria they do not provide. I send them   XXXX    explanation of Benefits statement and never hear from them.   Last week i receive a notice from   XXXX   XXXX   to check my credit report. i check and see a derogatory and inaccurate remark and my score has gone down from  XXXX  or so to  XXXX .   i call  XXXX   XXXX   XXXX   XXXX   State Collection Services i sp eak harshly with a woman going by the name   XXXX  .Asking her how the hecvk does she have the right to send any information about me to anyone without notifying me first. Im mad as  XXXX  and she informs me  State Collection Services  called me 9 times and never were able to contact me.I ak her why not leave a message on my voice mail if you really wanted to get in touch.   She admitted that a real live person ... you know a breathing sentient person known as a human being had not done the actual calling. it was a robocall and robots do not leave messages.   Asked her why they did not notify me by a letter addressed to me and she unequivocally told me  XXXX   SPECIFICALLY requ ested no letter be sent.     Am i missing something here? Is this a business practice allowed in the  USA?    I informed her i would be making complaints and she said i could have   XXXX    fax them a statement to prove my side of the story. I requested  XXXX  do this and they said it was not their practice to do so as personal information could be revealed and they declined.     They have provided me with a statement of Benefits for the date requested and i would be happy to fax this to you so as not to reveal any personal information to back up my side of the story Will be requesting written documentation from this  State Collection Services when i finally do receive written notification from them  .... as  XXXX  said i would a week ago when i initiated contact.   .You know by actually calling them myself and waiting to speak in  English to   another live breathing thinking human being.      XXXX  also proudly stated  State Collection Services was  rated " A '' by BBB.   Why would such a firm associate themselves with  XXXX  who has " F " rating with    XXXX   Disclosing in formation adversly affecting reputation of credit worthiness with knowledge or reason to know information is false is not a practice which should be employed by a reputable firm or one who tries to impress others as being reputable.      XXXX  has never provided me with an itemized accounting to prove their statement. Is this normal practice or a form of double billing and intimidation?     If  XXXX  had provided me with an accounting and they were correct i would pay..as i have paid every other legitimate bill i have received the past  twenty y ears.   i have never bounced a check nor have i been late on any payment in any account in  fifteen years  or better.
