Subs allowed without my consent

Hi There,

I am using my work's data card and of late I have been in trouble for using quite exorbitant amounts of data, our IT department pulled my usage records and they showed that I have been subscribed to MyCoolMobi http://mysocoolmobi.com, INCREDIVIDEOS, and VIDSMILE and are getting billed the following amounts daily R8.77 , R17.54, and R8.77 . I would like to categorically state that I have not subscribed to these sites or services and request your assistance in stopping these billings / resolving this billing issue.

The sim on which this billing was taking place got lost in the past week, but the number there of is OLD SIM: ********** ********** 385910.

This started in May and now I have to pay back these monies, monies that were ************ly billed. I want these data charges reversed and won't rest until that is done.
