Telkom Poor Service & a time competitive behavior

I ordered Telkom Fibre in September 2018. To date no Fibre has been installed. Out of desperation I cancelled every Telkom service, so that my line will get released into the holding pool. From the 22 January 2019, 8 weeks later and many calls to the sales and billing departments requesting that my line gets released, nothing gets done. Promises of escalations and manager call backs have all come to zero. Now it’s the retentions department that can only do it. Well they are doing nothing, one way to destroy a relationship and retain a client, just do nothing. I have no internet & no one at a Telkom can help. What are my options?
