No Answer from Telkom

Well, my contract ends in 3 months with Telkom, and i had a sales person contact me wanting to sell a new Fiber deal to me, i then said it should be fine, and he said it will be active early next week. Well on Tuesday i tried to call the Telkom center on 10213 as instructed by the technical department, only to hold on for more than 35min with no answer, and as we speak i am holding on again for Telkom 10213 to answer, this will be the 2nd time today i have been holding as the 1st attempt was for 25min, and now i am on 10min again, if this is the kind of service i will receive Telkom then i cant be with them anymore, and i cant even cancel my contract as they dont answer the call.
