Very Annoyed!!!!!!

I ordered a pot set some time in June and shortly after that the post office had a strike as a result I couldn't receive my order. My June statement already reflects the costs of the pots that I haven't received and to top it all , I am receiving calls from rude agents demanding a back payment. Today I got another call and when I tried to explain my situation the agent went on to say they have it on record that every time they try to call and solve the situation I am being rude? Excuse me, being rude.. no wait.... she then went on to say I must remember that I am the one who contacted Home Choice for the order, How on earth can I not be rude when I am constantly getting calls from their inexperienced agents with sticking attitude?
