Billing query unresolved

Telkom refraining to supply me with hard copy specified accounts, or contacting me to resolve my account. Additional costs was added to my account, but due to the fact that I have no access to internet, I can't find the supposed e-mailed account to find out what the added cost was on my account. I refuse to pay for something that I do not know what it is, and I know for a fact that the amount stated by the query department is due to calls made by myself. After visiting the Telkom offices, and asked to be contacted to resolve the query, no contact has been made. In the mean time my service has been terminated. Telkom service has been bad in the months of January to March due to heave weather - wind and rain storms. Various times I was left with no service due to lines not working. When reporting the lines not working, the assistant actually tested the line and confirmed the line not working. Once, when the technician arrived at the premises, the line was working again. Could this be a case of charging the client a call out fee when the fault was actually a Telkom failure? Can a assistant in the billing department please contact me to resolve the account?
