Pathetic service once again

After numerous efforts to contact Telkom with regards to my incorrect billing date as well as my cancellation, it's now 60 days and no help received thus far. I previously left a message here, and they responded with a reference number and they promised they will escalate to billing department, it's now 60 days and my account remains in arrears as I await my correct billing date and amount. Telkom customer service is pathetic to say the least.
