Service delivery what's that????

I am appalled at the lack of service I have received from my bank who I hold mutiple accounts with!!!! Clearly I need to make a change. I have sent numerous emails, complaints and phone calls and still no resolution.

My bank card expired in November and plenty of empty promises for delivery and it is the middle of December with Christmas approaching and I have no way to purchase or make any payments as I have no working cards. How is this acceptable?????

How do I put in petrol? How do I buy food? What am I supposed to do???
