UPGRADE DISASTER!!

Recently upgraded all my contracts (was phoned by eager consultants 4 months before the expiry of my contract which was a bit strange). I was hesitant at first because of all the bad experiences I have had with the company before. A major issue developed shortly after upgrading 2years ago. An 'out of the blue' astronomic data usage bill! Only after 6months (with hellopeter's help) the branch paid for it because insufficient product info was provided. After the event I paid Mylimit every month - still being very careful with it, checking it regularly and only using it for when I don't have access to my ADSL line. Monthly bills can substantiate that we almost never used all the data and had a perfect track record for 2YEARS and before! Received excellent service from two ladies who convinced me to upgrade. Surprisingly, ON THE DATE OF THE RENEWAL the usage of the same data card sudden downloads 4G of data and another 2G over the next 2days! How strange? Coincidence? The rest is history- endless calls trying to reconnect my phone (although monthly subscription up to date) while waiting for dispute feedback. I am so sorry that I renewed my contracts.
