poor service no feedback

Telkom the most pathetic service provider ever. I called your helpdesk 4 times already for 3 weeks to request invoices from when I took out the contract as the invoices sent out the balance does not make sense. I spoke to Lehlogonolo who told me the system was very slow and will send me the statement..nothing happened.after a week I called in again another agent logged a call for me ref# ********** 3 after a week received a message that matter is resolved but still no statements. I called in yesterday spoke to Tebogo who promised that I will get statements by close of business yesterday as they were downloading slow...guess what still nothing. I regret ever taking a contract with Telkom. poor poor service ever. no one wants to take responsibility in that company. I keep on following up but nothing is resolved after 3 week. Is it that difficult to get statements.
