Poor Customer Service Response

I find it very concerning when I have issues with my profile, then there is no prompt/quick. But I've received phone calls from RCS encouraging me to increase and offer other products. I require my profile to be sorted out asap. I'm unable to log into my profile due to exceed limit exceeded. Also when I utilise the services by swiping the card at various retail stores, there is no security in prompting me to enter in an pin. I need assistance as I find this pathetic. I expect feedback soonest.
