So, what language to Skype support speak? Because they don't seem to understand "my Skype isn't working"!!

Very VERY frustrated now - for 3 weeks, I've been going back and forth, logging problems about not being able to get a confirmation text to set my SMS number.
Basically, it goes:
Me: "My sender ID has reverted to the username and the verification text never arrives".
Skype: "We are pleased to see you have resolved your problem" OR "Here's how to set your sender number".

God, they are so DUMB! Or they just simply don't read the question. It's incredible, and incredibly RUDE to me, Can someone here PLEASE give me some support?
