How rude can you be

I have been a client of yours for more than 10 years and over the course of the 10 years I have been exposed to horrific customer service that was mostly rectified by you in some manner until this week. <br> After receiving a variety of messages and a few rude phone calls from you I went to your Brooklyn Mall branch to upgrade my contract. So many things went wrong that I will now continue this letter in a numbered manner to ensure you follow. <br> 1. The phone I ordered was not available. I can understand that this can happen so it was not too big an issue. However, the manner in which I was handled in both your Brooklyn branches was shocking. <br> 2. Your sales assistants have no communications skills, they do not know how to use their words. Unfortunately I am not fluent in hand gestures and nose scratches and thus have no idea what the answers on my questions were. Simple things like when will the phone arrive, can I get it from another branch (they were not willing to help me on this point), will the deal be available next month? I believe these are not difficult questions and could be answered in a polite manner. <br> 3. I have been to the Brooklyn stores 3 times in the laste 3 weeks
