Don't change a winning game!!!!

Last week there was a problem with their online banking - the problem was on their side, but there was no pop-up advising me. I did get a response from them from a very efficient lady who phoned me a few times to make sure the problem was resolved. This week - more problems - the online account has been changed, AGAIN! I made a payment, but suddenly the "download proof of payment" option is no longer. Why?? Why do they keep on changing it!!!! With so many irritations in our lives, this fills the bucket to overflowing . Infuriating!!
