SHOCKING SHOCKING SHOCKING SERVICE

I have a medical practice in Cape Town. Have been a customer for 30 years . We requested cancellation of our ADLS line ONLY. This is how the form was filled in and in addition this was written IN BIG CAPITAL LETTERS at the top of the form. So now they cancelled THE ENTIRE SERVICE.!!!!!! We have reported this to them daily-the call center is pathetic-they have done absolutely nothing to restore our telephone line and you can NEVER get any responsible person to action and feedback WORST CONSUMER EXPERIENCE OF MY LIFE.
