Impossible to open investment account

I am trying to open an investment account. It is such a complicated and convoluted process - not user friendly at all. I also have dialed their number a few times per day on a few days - I enter my ID # as requested - then nothing happens. I am wasting time. I also submit documents - only to get messages to submit those same docs again - and again ..... I also think it is ridiculous for a bank to only do banking on a phone or tablet - I certainly prefer my large monitors coupled to my laptop.
