SALESMAN NEED SALES

I have been with Vodacom right from the start. Have about 8 contracts with them for bussiness purposes. Always had good service and feedback, but this latest incident takes the cake. My blackberry Z10 packed up two months prior to upgrade on a red premium package. Went to my nearest Vodacom outlet and told them of my problem withy the z10 that just froze. They informed me that they could send it away for repairs, thus beeing without my smartphone for several days. They also said that there is a good possibility that it was irrepairable. I then asked for a upgrade on one of my other contracts as i was sure there should be a contract upgradable. The lad told me that there was none and the only option would be purchacing a new phone at a astronomical price or a new contract. Eventualy i was convinced by the salesman that a new contract was the only option. I took out a new contract at R249 per month for 24 months in June 2015.In January 2016 I went to the same store as the red premium was upgradable in December and upgraded the contract. The saleslady then told me that another contract was upgradable in 2013.This leaving me with the question as to why I was sold a new contract . Space
