Numerous complaints and no help, now number suspended

I've been with Telkom Mobile for 6 years. I have always paid via EFT. Last year I upgraded my contract via a call centre.

In August 2017 I started getting fees added to my bill for R200.94 called "debit order rejection fee". Same thing happened in Sept 2017 and Oct 2017. I still pay my subscription due each month as I should but I haven't paid the R200.94 x 3 Disputes are just ignored and my service was suspended last night.

Telkom Social Media helped me on 2 Nov already but no progress, reference AI **********
