A simple task disastrous

We are a corporate. We have 3 voice accounts with Telkom. I have asked for the billing of invoices to be changed from post to email as this makes it easier for all parties involved. From February 2015 I have been asking for this but nooo I keep getting referred from one department to the other. This Buti guy doesn't to give any ****s at all. When he came to our offices he promised us to handle our account with care as our Account Manager because then he wanted our business. After Telkom gets the business this is how you guys treat your clients? I mean how hard is it to change billing from post to electronic with all the required documents? Hehe this is my business finding another service provider.
