Repeating calls at work after employer instructed to stop calling

After trying to make an arrangement I was topd my arrangement will not get accepted and they WILL continue to call me. After numerous requests to remove my employment numbers, I was, LAUGHTED at. We ARE NOT ALLOWED PHONE CALLS ON OUR WORK NUMBER. You caused me to sign a written warning after repeated calls to the office. When my employer instructed to stop calling the work number, guess what also laughted at and call dropped, just to continue calling the land line hours thereafter. They picked up 9 calls to the office from YOUR people!!! I responded on the mail what I can pay till in a better position, but you get arrogant responses back. I said when I am allowed to take calls, your agent telling me "not their problem"!!! You will cause me to lose another employment we cannot afford as we already only have one income with your phonecalls at my work, telling them you are calling from an attorney for collection!!!!!!! YOU MAY NOT EVEN DO THAT!!!!
