Lazy and unprofessional

I baught a fridge on 19/06/15 1st payment was to be in August, on 21/08/15 I recieved a call from bradlows debt collectors who informed me about being in arrears i I made the relevant payment arragement on 25/06/15 I recieved a call from cel.no. *** from Maria bradlows Protea Gardens she told me that I am in arrears and wanted to know when I will pay, I told her that I could not talk but bradlows collections have already called me she must liaise with them, she said nothing has been said to her so I must repeat what was discussed with collections department, I told her I was in class so she must phone the relevant people. 26/08/15 Maria sent people to reposess the fridge even though I had made an arrangement. this caused comotion, stress as well as embares***** t for my elderly aunt who I have baught the fridge for. All because of Maria was too lazy to call bradlows collection department. Luckily the repo agent Mandla was kind and reasonable and gave me a chance to explain, he apologised and gave me his bosses tel no. who also said would clear it up in the morning. Maria must be reprimanded and trained in good customer service. I
