Local Splash Charged my card 4 years after I said no to their service Costa Mesa California

 On January 26th 2017 at 6:39pm I received a "large purchase approved" alert on my credit card that. It was from a company called Local Splash, I was baffled, I had no clue who this company easy. I called the number to dispute this charge. The woman told me not worry that their had been an error in the bill and my account was accidentally charged and she would issue me a full refund. Phew. Okay. Next I asked her why her company even had my credit card number. She said that sometime back in 2013 I was contacted by a rep of theirs who wanted to see if I was interested. She said it sounded like I was interested at first but later declined and asked them to cancel my account. In 2013 I was running a business so it is quite possible this happened as I did receive many of these types of inquisitions. So I asked her why my information was still on record and why, almost four years later, I would be charged $516? I don't even own that business anymore. She said not to worry and assured me the money would be refunded. Well, this morning, at 10:30am I received a notification they refunded me account, only $99! So, I quickly contacted my credit card company to dispute this as well as send Local Splash emails letting them know I'm going forward with this manner and I will get my lawyer involved if it comes to that. I did further research online and found that this company is constantly pulling scams like this on people and I am baffled they are still in business. Who keeps someone's credit card information saved for four years and then bills them to a rather large sums of $516? Who does this? I'm hoping this gets resolved ASAP! Be advised DO NOT get involved with this company! Im surprised they are even allowed to stay in business!
