Upgrade my LTE contract

<p>In January 2014 we app**** for the LTE service with Telkom. I got a call from Shaheen from the Telkom Call Centre. We did the whole process over the phone and he confirmed its a 12 month contract. So in June 2016 this year we decided to upgrade from the 10GB to the 30GB at the same price. We went to the Telkom shop in Mall @ Carnival and spoke to Maria. She said that we can only upgrade in October 2016. So in October we went back to the same store in Mall @ Carnival and spoke to Kash, who I must say was extremely rude, and kept interuppting me while I was talking. She told me that its still not due for an upgrade as this is a 36 month contract. So we went from a 12 month contract to a 33 month contract to a 36 month contract. I am too scared to go and see them again in case they decide that it is now a 54 month contract or a 60 month contract. I have been trying to get hold of the call centre online, but they just ignore people. The product is amazing and we have never had a days problem with it, but trying to upgrade has been a nightmare. This is absolutely shocking.</p>
