Pathetic Call centre agents

Due to Covid I have had a cash flow problem and I have been trying to make it right by paying something towards my account. The service from the service agents are lacking to put it mildly. Many of the phone calls made to myself there was nobody on the other end, I have had missed call that hardly ring and some calls when the call agents are shouting to each other without speaking to me. I have been requesteing banking details for a while now and nobody will send them to me. I have requested telephonically, via email and return sms. Now you have handed me over. Firstly do you know what is happening in the world at the moment???? Secondly send me your DAMN banking details like I have requested many times. I would complain about the service, but I cannot because there is none......
