Telkom Account Issue - Exhorting Money from our company

Telkom Business account needs to be closed and moved to a new account with a VOIP Phone. Now Telkom is exhorting money from me by let me pay for two accounts. Emails have been send but no reply. This is not good customer service and treating a small business. I need urgent response on my account queries and emails sent to Telkom> Q: When will we receive the VOIP phone to connect to the new router? Q: When will you terminate the current account in order for us not to pay for two accounts at the same time? If not resolved, we are happy to go to another service provider. Urgent response is needed.
