How do I cancel my subscription? - free trial ends today

who do I contact to request that the cancellation of my free trial - paid subscription starts tomorrow. 
I have uninstalled the sofware and do not wish to use it and I don't want to be charged. 
I cannot seem to find a way in which to contact directly a person who can help
Any advice? 
Please help
