Helpchat is the worst app, it's biggest problem is sever.
coupon was used only one time and the second and third time not used when we apply it shows already applied just. my personal experience this is afraudulent company who cheat people by offering Cashback which never gets back to.
Nearly 10days back , I tried to recharge using
HelpChat app, At that time I was needed recharge very urgent. So I have been trying recharge nearly for 10 times . All the 10recharges were failed . Still now I didn't receive any refund from HelpChat.
