Omitting important information!

To say I am extremely disappointed in Vodacom's service is an understatement!! I received a call about a year ago offering me a reduced rate on a special deal they had going at the time. Seeing as this was months after my contract had ended, I assumed this was an additional offer. About two months ago, my phone started giving me issues and I was now ready to upgrade and renew the phone contract I had. Once I had done my homework and decided on a package, I contacted Vodacom to upgrade only to find out that the data deal they gave me a year ago was an extention of the existing contract I had! This is surely unacceptable as the person I spoke to neglected to mention that this data deal was extending my existing contract for another 24 months!! Why would I only want data when I've been using airtime, etc. all along?? To top it off, the package I wanted was a Black Friday deal which I have now missed out on because I couldn't renew due to Vodacom OMITTING IMPORTANT INFORMATION when they extended my contract without my knowledge! I have been with Vodacom for over 10 years now & am not looking to cancel my contract/business, but I simply want to upgrade my old contract without being charged a penalty for this existing one as this is the fault of Vodacom and not mine. This will increase my costing with Vodacom and therefore should surely be beneficial to you. Please can I be contacted immediately as I want to upgrade my phone as soon as possible!!!!
