Telkom incorrect disconnection not resolved

I cancelled my Telkom line and internet connection on 1 May (giving a month's notice). I asked that my email address be retained. I was incorrectly sent accounts for May and June. At the end of June my line and email was cut off for non-payment. I queried this with a very helpful call centre operator who emailed the "fixed retentions escalation" to whom I provided all evidence of the cancellation. It is now nearly a week later and the matter is not resolved. I still cannot get my emails. They say they have tried to call me, but ignore my request not to be called (I can't take or make calls during the day). I am now desperate and completely furious at this poor service. How long does it take to reinstate a service and fix a problem. Seriously? Why was my cancellation request ignored?
