Unwilling to assist

My partner changed his phone number recently and talked to Standard Bank Shyft regrading the change. As per Shyft he has a Standard Bank account and this must be done at a Standard Bank branch and they are unable/unwilling to assist any further. He does not have a Standard Bank account other than a Shyft account. Please let us know what account we have so we can draw the money out of it (hopefully there are millions in that “account”). It is a point of concern that you keep on telling us we have an account but you cant back up your facts. Rather get FNB Global account as it seems as Standard Bank is living on Mars.
