On March 8th I was contacted by this company with a sales pitch on their magazine. I'd never heard of it. I was busy with a client but the caller could not take a hint that the timing was poor, hindsight I regret not just hanging up. I told them that I'd like to receive information before committing to anything. After initial contact from them by email, March 16 I sent a email stating I was NOT interesting in participating. March 17 I received a email where I was tagged and the employer was telling them to change the add layout as the initial did not contain my buisness logo, and to submit for review. They completely ignored that I'd said NO. On Apr12 I received another add proof. I again emailed and said I'd clearly said in March I was NOT interested. At this time they informed me that during that Mar 8th call I was entered into a 72hr window to cancel the add. Meanwhile I'd NEVER agreed, I'd requested more info. I do not want this company contacting me anymore. They repeatedly have been sending invoice bills by email and letter. They were not given a deposit of any kind. I'd said no after the initial email they sent. They are trying to bully businesses and this needs to be stopped.
