My Store review for EM: SMS,FB,IG,Email Marketing

I have been trying to get in contact with them for over a week I've emailed I've text the help desk which says they reply in 24hrs its going on two weeks no response i cant even disconnect the app from my site until they do and its holding my launch date up I'm really sad that this is is how they treat there customers and that shopify uses these type of apps for there customers
