Cancellation of mobile service is mission impossible

[cloud]

I am trying to cancel the mobile service as i applied the sim plan for my mum to use and now she moves overseas. I called and was told to wait one day for them to call me as they are extremely busy. and was told to keep my phone at hand as they are going to call anytime.  While I insisit as I can not answer their call during a meeting, they JUST HANG UP MY CALL.  

I describe the fact that just happned.
