Telkom Webhosting and accounting sucks

Telkom did our webhosting with our email addresses. So last year around July / August they lost a lot of our emails and we did not know what emails did not reach our clients and we did not know what emails we did not receive. They could not help us so we decided to go to a smaller business that could talk to us. We have been with the new company from August but are still receiving invoices. I phoned Telkom and after one hour and 45 minutes and 4 different people I got a reference number for my query. I followed up 2 weeks later just to hear they cannot help me I have to email hostmaster again. That never goes well but I am emailing them now daily.
