Vendi Vintage review for Mailmunch Forms for Mailchimp

HORRIBLE APP!!! I just paid twice (accidentally) as I thought my payment didn't go through..my bank card was charged twice and after logging out and logging back into my shopfiy shop, it kept wanting me to upgrade my plan, I spent over an hour with Shopify and MailChimp email support to no avail no help whatsoever, no body wants to work or help. These desk support people are lazy and do not read thoroughly and give you some printed, quick, resolve that has NOTHING to do with your issue! TERRIBLE app and equally terrible customer support from Shopify! So disappointed!
