I ordered the set of 3 tree tomatoe plants from an online advertisement for $10.00, and received 3 plantingpackets with "seeds" in them. Somehow I inadvertently must have clicked on something I never intended, because my bank card is being charged $14.95 per month. I have not been able to make contact with ( SB*savings2go) either by phone or the internet to cancel this charge. What can I do?
