Telkom sucks

Trying to resolve a billing issue with telkom for the past three years. Have 2 accounts. Both personal. Both have landlines but one has fibre with it. The fibre is connected to the correct line at my residence, however it is billed on the other account. This creates additional charges as a result due to the non recognition of the home unlimited package on the line. I called the call center gazillion times, same story. Sales says all in order on their side and its a billing issue, speak to billing, they say it's a sales issue. Spoken to managers on both sides, not resolved. Went in Twitter, told its resolved, but it is not. I want to to transfer the one line n get a new service but I can't due to billing issue not being resolved
