So frustrated with what Dell calls "Customer Support"

I am so tired of having to deal with a group of people whom don't understand the language (English), don't speak clearly enough to be understood, don't speak loudly enough to be heard, or type using poor grammar. Every time I encounter "Customer Service" I encounter endless holds while the person on the other end tries to figure out how to do what I am asking them to do or just flat out doesn't have a clue. I just tried to update the expiration date on a credit card used to make a purchase. I entered it wrong, so it was my fault. The call to fix this took 19 minutes of actual conversation time. The representative picks up the phone and asks to put me on hold. I told her what was needed 3 different times throughout the conversation. She came back and said the payment didn't go through. I already know this as that is why I called; to update the expiration date so the payment would go through. Finally, the third time she gets it. She puts me on hold again. Is your system so poorly designed that it is that much of an effort for your representatives to make a modification to the payment method? Then you have the two conversations I have had in separate online chat sessions over the last two days. The same person, both times, cut off the conversation before I was finished. I call the customer complaint number only to be told "I don't have access to that part of the system, but I will pass along your feedback.". I truly expect you to do so. (sarcasm) It never fails, every time I have to contact Dell support I have to waste so much time and get passed around. I am done purchasing through Dell. No more servers, workstations, laptops, or switches at work or the house. There are too many other companies I can buy from and get service that doesn't waste my time and stuff up. I would say it is a language barrier, but come on. How long have we had to deal with different nationals providing "service" only to see the whole process get worse and more frustrating? At what point do we STOP cutting corners on cost and put a little bit of a premium on quality of service? Give me someone who understands English, can speak it clearly, and MAYBE even understand grammar so when they speak or type the meaning is clearly understood.
