Hello! Thank you for choosing AcmeBrands. How may I assist you?
I hope someone can help me! Every time I try to buy an item from your store, it's always out of stock! This is unacceptable, why can't I just give you my money like a normal person!
I'm so sorry about that, I can imagine how frustrating that is! May I ask for your full name, please?
My dear friend David Williams Esq. was right about this site, out-of-stock every single day Rodriguez Domingo is my name.  Of the Greenwich Domingos
Ahhh yes, your family is very prominent society! Mr. Domingo, I will be happy to write up a report and let the Purchasing Department know about this issue. I agree that it's most untenable.
I should hope so!
I understand that it may not satisfy your displeasure entirely, but I hope that it will suffice for now. Is there anything more that I can do to meet your satisfaction?
I suppose it will have to do No, that appears to be all
I sincerely apologize for the inconvenience! Thank you so much for contacting AcmeBrands customer service. Goodbye!
