Call Centers in Singapore are terrible

I am so frustrated trying to communicate and get help anytime I do a chat session or phone call.  The call centers seem to be based mainly in Singapore and it is terrible service.  They do not have a good command of the English language,  they do not know how to do anything but go through a script,  they keep repeating things over and over (i.e.  "No worries I am here to help you" and "Thank you for that").    I have spent a ridiculous amount of time trying to get help and after several hours I still have not been able to get any help.

And they hang up on you when they realize that they do not know how to solve a problem or they do not understand.    

Please bring your tech support,  customer service and call centers back to the USA where they belong.  I don't live in Singapore.  I live in the USA and prefer to deal with US Citizens that know how to communicate.   And you should be bringing these jobs back home to the USA.  Employ US Citizens.

I'm at the point that I want to cancel all of my xfinity services and throw all the equipment out the window.
