Charges and debits with vague descriptions on my account

This morning I tried to query some charges and debits on my account and an agent by the name of Arthur ignored my message and proceeded to ask me what he can help me with. I then sent a response that I had already detailed my query in the previous message but this message would not go through even though my network was working fine. I was then told that the chat will be terminated because I am not responding. I also tried to add a payment recipient and the system would not give me the option to add a bank approved recipient, only to search and see that the recipient exists as a bank approved but I cannot add it to my recipients in order to effect a payment

To think this is a bank that has been in operation for many years yet they can't do even the basic things such a having a proper functioning internet banking or mobile app service.
