Disappointed in telkom

We've been loyal customers of telkom for the past 40+ years. I live in a rural area in kzn. Telkom has decided to change their systems in rural areas, which is totally understandable, what isn't understandable is why us customers have to pay for this change. We didn't ask or request for the change. Paying for the new system is also somewhat justifyable, what isn't is the amount and also the monthly costs, it's ridiculous. We can barely afford the normal phone rental let alone this crazy amount. It's really unfair that people in rural areas have to pay for this when other customers don't. Telkom is a service provider, and have a duty to provide the SAME service to all their customers regardless of where they live.
