Vodacom takes down the my Vodacom site month end

I am so sick and tired of not being able to log into my \My Vodacom\" account the last 3-4 days of every month. ALWAYS a message of some sort with \"try again later\" Do you do this purposely so that we cannot any transfer any airtime or data from one of our numbers to another and so you force us to buy more data for the number we need it on?<br> Sick of it. It's *********."
