over promised but undervalued customer

I have app**** for a cellphone deal with standard bank the chat consultant told me that it's processing just holdup from delivery side.I app**** on the 9 june and today is the 23 if I didn't call or follow-up I was basically pushed from pillar to post I bank with standard bank have a credit card have a loan cause of standard bank not debiting my account on the chosen date my credit score dropped to 550,standard Bank has in no way valued me as a customer I need a cellphone so desperately thinking banking with yourl so many years I earn a good salary I would get the phone I want I had spoken with consultant over the phone which also assured me of delivery but just left disappointed.after many many years banking with standard bank fnb has approached me offering me the phone that I want yet I don't have an account with so thank you for nothing will be considering changing in the future as they say change sometimes is good if one is not valued
