Robo Calls PK

Worst experience ever. not recommending to anyone, they charge you extra than usage and after shopify bill generation you cant do anything. I've used their 3 apps for 1 month out of which only 10 days app works fine, they don't have any customer support neither any reasonable answer other than ''we will reach you tomorrow morning'' and that morning never comes. they send you a review template at the day of installation and ask you to post their created review on their apps with 5 Stars. There are so many things they do other than fulfil your requirements. Very Disappointed .
