Signed up for SDrive without concent

I see other people are complaining about being signed up (*******ly - i.e. without explicit content) for SDrive. I received a call a few weeks back from a call centre operator about some new product, the line was really bad so I wasn't quite sure what the product was. I was happy to oblige when the operator told me she would email me with information. Just before she ended the call she said, \Welcome to SDrive!"I was so shocked"
