Suspended Telkom landline account, due to billing error

Hi. I changed my ADSL package from telkom to a new ISP in Jan 2018. Telkom changed my account number for the landline rental without informing me. They then billed the old account number which resulted in the new account number showing that the landline was not paid. They subsequently suspended my landline on the 26th March 2018. After numerous calls, online chats to agents, I finally got a proper answer on 29 March 2018 from telkom twitter support page saying they billed the wrong account and the funds will take 7 to 14 working days to fix. This is not fair towards me as i need the internet connnection. Please assist me by speeding up my recconnection.
