Pathetic telkom service

Where do I start. I am having the worst experience of my life with telkom. I was on telkom fibre and I hav a landline. I cancelled my fibre 2 months ago and was told this will not affect my landline. From the 27 sep my landline is disconnected and everyone gives me a different story about what to to. I am so tired of this poor pathetic service. Can a manager at telkom call me
