Disappointing service and terrible lack of feedbac

About a month earlier I contacted the Prestige line to report a fault that I was no longer receiving the myupdate Sms notification for my transactions. I was put through to the myupdate division. I indicated to the agent I spoke to that my phone (Samsung Galaxy Note 4) did not change nor did my network change but the myupdate Sms's were no longer coming through. He did a bit of troubleshooting with me over the phone but he was unable to resolve the problem. I agreed on the interim to switch to email update even though this was inconvenient while he addressed and investigated the problem. Until now I have received no response. Absolutely terrible Service with no interest shown to the client. Very disappointing. This is not the type of service I associate with Standard Bank.
