Hello, how may I help you? -NOT!

So, this is probably the 1000000th post about the futility of call centres, but here's the 1000001th one. CALL CENTRES are POINTLESS. Vodafone call centres to be exact. What part of 'we will get back to you in 72 hours' do they not understand? Perhaps they have been having technical difficulties for over a month now. Or they could be having issues with their mass messaging. Or they could be just plain LAZY. The third one being more probable. They tried to talk me out of changing my phone package and I took the one they offered because it actually made more sense. And they didn't do what they said they would. So I hauled myself and all the documentation required to the store to change my plan. I am proud to say I DID NOT LEAVE until i got what I wanted. Definitely passed assertiveness, I was aggressive as hell and got my point across. Needless to say, I now have free text messaging for a month!
