They don't deserve to be called a bank

This is my reference ***NF and I'm still making a follow up on the complaint I made 5 days ago and they said they will call within 48 hours but they never did.

This was their responce 5 days ago "Dear Valued Customer

FNB High Priority Complaint reference ***NF has been sent to Customer Resolution Centre. ***.

A Consultant will contact you within 24-48 Business hours."

They even had the audacity to call me valued customer while they don't value their customers at all.

Well I joined FNB recently from another bank, the bank I left was not the best but with customer service they were doing all they can.well i have been trying to make an online transaction which was due 8 days ago,my card keeps on declining, even tried transferring money to my Skrill account but it keeps on declining. When I call they tell me about using the app or transfer me from one agent to another, I have lost a lot of airtime calling them, they don't even respond on their securechat neither do they return booked callback.after I made a review on hellopeter they said they will call me which they never did. I'm still on work holiday and when I return to work I'm closing this stupid account, all the days of my life I have never seen such bad service, they are Specialist in bad service and I still haven't made my transiction which was due last week because of this stupid bank, why blocking my account on the first place?
