Call Forwarding

My husband has written countless reviews and lodged complaints regarding the fact that even though he is paying his contract on time every month, for some or other reason, Vodacom has decided that we should not be receiving calls. Every single one of them gets forwarded. Now, and bare with me here as this becomes rather interesting; he speaks to a consultant and she tells him that she sees he is not registered for "Caller Identity". It is free to prepaid customers but costs R10.00 for contract customers. My response: "R10 sounds really cheap but why would we need to pay for such a service? Isn't that just a little ridiculous?" Well, Vodacom does not think this is ridiculous and since we did not opt for this service, we are still not receiving calls. NOT ONE SINGLE CALL!!! REALLY VODACOM!!! YOU ARE BLOCKING MY CALLS BECAUSE YOU WANT MY R10 ALONG WITH ALL YOUR OTHER CUSTOMER'S R10'S?? JUST HOW MUCH ARE YOU MAKING BY EXPLOITING YOUR CUSTOMERS LIKE THIS?!?!? PATHETIC AND ABSOLUTELY RIDICULOUS VODACOM!! I REALLY DID NOT EXPECT THIS FROM YOU!!!
