Smart Shopper Card Service Sucks

I am dissatisfied with PnP smart shopper service. I have been asking their customer care to assist me with unblocking my smart shopper card and also to assist me with getting my username and password to sign up with their app. I have shopping that I need to do as I am at home on maternity leave and cannot drive to the shops. I've been asking them for that past 2 weeks for help and I just get ignored. I receive better service from Checkers and think I should rather do my shopping there as they also do the delivery method now.
