Poor service on Cancellations!

I logged a complaint earlier this year, in Feb to be precise, regarding poor network coverage, and data signals. A claim was logged and person was sent out to my house - problem is, my signal is fine at home, but I travel a lot for work (consultant for Discovery), and now my signal gets lost on the road when I need to make work related calls. That's why I took the Unlimited contract in the first place, because I am on the phone permanently with clients and financial advisers. Anyway, I went in to cancel my contract on Tuesday 28 April 2015, was CC'd in the mail and told that I will be contacted, No one made contact, and on that Saturday I went into the branch, and confirmed that my case was logged but not attended to. I then sent out three emails, this a week later, but no reply. The call centre then helped me and said they can see the emails, and it takes 4 to 5 working days to attend to cancellations (it's already been 8 days!) , but on the system it says my case is deferred and unattended - They said I have to call each day, with my case number ready, to follow up until the cancellation is made. CASE NO: ***7.<br> <br> This is shocking service to say the least!!
