No resolution to open dispute

In Sep,I migrated my landline from a top-up to a fixed line.The 1st month, my bill went from R200 p.m to R1600 and I raised a dispute, which to this date has not been resolved.I called to request a statement only to find that I was charged double fees for the 1st month and installation fee of R694, I was never advised of this costs or given the choice. I called on the 27th Nov and Precious advised that in order to open the line I need to pay R2103.25, which I did on the 1 Dec 2015. She also logged the 2nd dispute.by the 3rd Dec the line was still suspended, I called and they said the line is open. By the 4th the line still suspended So I called again and told that it was open, the consultant raised a fault with the tech team ref: [URL Removed] called me on Sat advising that there is no tech issue to call billing as there is still a one way suspension.So I called again and spoke to Amanda from the Billing department. she found that I still owe an amount of R464.04 for Dec.The 2iC gave permission to open my line until the dispute was resolved. the request was sent to the back-office to open my line.my line is still suspended
