Email and internet line not working since 21 dec

I have logged many complaints as well as a hello peter with no response. Our business email was deactivated from Telkom side on 21 Dec 2015. After many calls and promises to be phoned back it is still not working 4 months later. This has cost our business losing all of our clients emails for orders. Our internet line has not been working since end of December 2015. You can trace all of the calls that you record to see infact that this is true. Now I can not get a credit note for this. I refuse to pay the internet and email line for the past 4 months and will not pay my account until this has been rectified. I can be contacted on [Email Removed]
