RCP ON HOLD - NOBODY KNOWS WHY

I have had an RCP account since 2002, paid up and closed in 2012 and reopened in 2013. Two years later I get told I cannot have an advance account and a revolving credit plan and a stop is put on my RCP. No calls from Standard Bank, no explanation, nothing and I go into my account and pay R4500 so that I can revolve again only for the transaction to be declined. This was on the 25 June, since then numerous calls to my Prestige Banker and emails only to be told sorry we cannot help you. Who takes decisions like this and does being a client for 20 years and more not matter to STANDARD BANK. All my payments are up to date and the personal advance account has never had a returned debit. I have other open cases for the past three months and no joy. Totally fed up with this *********** interactions.
