Upgrade ****!

Telkom mobile advertises on they brochure and online for free unlimited calls to telkom mobile for the first 12 months of your contract. Thereafter you may purchase it for R50 p.m. But if you upgrade you get nothing! Not even the option to purcahse it for R50 p.m. How is that an upgrade? Thats more like a downgrade!!! That is really unfair because no one at the branch explains it to you and it doesn't not specify on their booklet fine print As well!!! The only reason i had the network was because of the calls. Now it's not even worth it. What a *******
