STANDARD BANK OF SOUTH AFRICA CORPORATE - "CLIENT SERVICE CULTURE"

I wrote dozens of emails to Standard Bank of South Africa, but I am empty handed insofar as clear figures responses to questions posed to the Bank such as “what was November and December amongst other months the spot rate exchange app**** to my European pension income received by the Bank on my behalf?". One of the managers "Andrew"...."called it “the hot rate” but refused to reveal it and also refused to do an adjustment for a variation to the Rand amount I received to fix it". Another manager called Nolwazi also refuse to disclose these exchange Rates and blame discrepancies actioned on loaded instruction for transactions but DO NOT REVEAL what are those instructions and WHO and on WHO’s AUTHORITY were these instructions loaded!!! Clearly this is the Bank pocketing profits with slanted rates for its *****ulent advantage of top and over charged fees for transference services always concomitantly app****. I am looking forward to receiving figures to ascertain the average losses I have been incurring but no one takes responsibly for blunders which can be constructed as ***** and DO NOT REPLY TO my emails – Yah I am just the Client who cares for Clients at STANDARD BANK OF SOUTH AFRICA?
