"We apologise to those impacted for any inconvenience, and appreciate their patience.”
"Why are both the app and Internet banking platform having issues once again?," one customer said.
"And it won't let me to use the chat option. Hsbc you need to sort this out!"
Another said: "HSBC online banking payee selection option down. Essentially means their online banking is totally down."
Responding to one customer, HSBC said: "Hi there . I'm sorry you are having issues with the App. Give a call our Online banking department on 03456 002 290, the team is open from 8am till 8pm. They will be able to help you regain access to online/mobile banking."
