About 3 weeks ago, I began getting Multiple phone calls, as many as 4 times a day from what shows on the Caller ID as RECEIVABLESPERF [protected]. They call at all hours, including after 9pm at night and on Sundays - which at one time were both illegal to do. The reprsentatives who call make threats and raise their voices. I have asked them several times to cease and desist with calling this number, but they refuse to do so. I want to know what action can be taken to stop this company from practicing business as they do.
