When do we get a capped monthly amount?

For many years, we've being held ransom by the Bakwena Zambezi and Stormvoel gates. Motorists in suburbs around these two gates have no alternatives travelling to Centurion, Midrand and Johannesburg. When do we get a monthly capped amount? I see that Bakwena doesn't respond in this forum, I therefore don't expect an answer from them. The purpose of my complaint is to create awareness to the injustice of paying toll fees to get out of our suburbs.
