Poor Service

I have had a dreadful experience with the treasury department of Discovery Bank to day 14th December 2021 Firstly trying to get through them is a mission, i had left messages for them to contact me but had no joy, then i finally phone them again and eventually got hold of them. I tried explaining my problem and he was not willing to hear me out nor was he willing to give me the email address where i should lodge my complain, he just cut my call off, that's poor service. Also people working from home should be told to keep the noise level in the background to a minimum or at least have a room dedicated to work from, in the interim until this is over as background noise makes it very difficult to hear when dealing with important issues... totally dissatisfied
