boely-ish- behaviour, verbally abusive and harrasment

these people dont collect debt, they get personal. they dont try and make arrangements, they try to humiliate you at your company, you tell them to call back in an hour as you in training and they will phone back 18 times in that hour eventually this escalates in to slam the phone in reception ear when reception tells them that I am not in or available... they swear management. it is boelish behavior non stop, being rude - it gone past the point of discussing payment is now harassments and verbal abuse... then they just say does not matter what arrangement you make next day someone else will call you because calls from switchboard automatically. I am now busy with attorney for this harassments they not trained to deal with debt collection, they work by threats, verbal abuse and making life hell at work. it is shocking
