Sitting aboard and no one is helping me #PrestigeBankingBADNews

I have been in touch with a few different individuals on email, and due to them all working from home they can not phone me on my international number - but when I phone and eventually get through I can hear them but they can't hear me - leaving me with a bill that is rediculous - then they ask me to complete my security questions on email?! like just phone me or give me a cell phone number that would work so that I can get things sorted - but no it's up and down with email and different people getting back to me with no solution; which I asked for help with on the 14th of July 2020 - and had the following people reply but not assist me: Selloane Mabaso, Nomvula Moorosi, Judith Maoka - I really don't know what to do anymore and how I will get this sorted at all!!! FED UP! Regards Nanette in New Zealand
