XXXX sent my bill to a third party collector for collection. Previously I requested an itemized bill to verify the amount owed was legit since it was an exorbitant amount XXXX I only received a bill for the balance owed with no itemization or details as to how that amount was derived.Now the amount is XXXX How could I owe that much on one phone bill that was being paid monthly without any interruption of services? I do n't have a problem paying I just need proof of what is owed in writing. If it is a valid balance why ca n't they produce a bill. ]?
