MVQ SavingsZoo.com review: 15 day trial membership 1

I received a letter in the mail saying I had a 15 day trial membership. At the end of the 15 days my account would be charged $23.87 a month. I could call or email my cancellation. I emailed it immediately. I have no idea where, why, or how I got this letter, or why it charged account twice.
I have emailed, I verbally spoke with someone and here it is today trying to charge my card. You all need to send my 47.74 back, that yall promised me to return. I get a whole new card and I only gave my cars info so you guys could refund me, but no yall keep trying to 23.87 off it. I'm not replacing my card again, I'll just take this to my lawyer.
Thanks Sebrina Allen
