XXXX XXXX calls from Summit Receivables at least once-twice a week. I do n't know what this debt is, but I receive calls from an unknown number from her and then XXXX from her XXXX on XXXX XXXX from a XXXX number XXXX and XXXX from her on XXXX XXXX from a XXXX number XXXX. In all the messages she leaves she says, " I 'm calling in regards to a file we have in your office ... ..trying to reach you in reference to this file. '' The message is very vague and then she wants me to call her at XXXX which is not the number she calls me from.
