Very Rude Consultant

On Sunday afternoon 14h00 I received a call from 087 number and I picked up, the lady who didn't even tell me her name said she is calling me from Homechoice and called my name. I asked her if she is serious to call me on a Sunday after I old her it is the right person. She started telling me that does she seem like she is joking? With a bad attitude. I then told her she is rude, she told me I am the one owing Homechoice and she specified the amount, and continued attacking me. I asked her her name and she refused before hang up in my ear. Firstly I bought their product supporting a colleague, who is their agent. But to receive such a harassment from their employee is uncalled for. They are rude. To even call on weekends calling it a courtesy call.
