Standard bank to not reply to complaints

Internet page for Standard Bank complaints: REf: ********** 345 I went into bank and spoke to the internet banking client services via the phone. Was told query was be addressed. NOBODY PHONED ME BACK. I then completed the online complaint form. A Mr. Jeffery Mphutlane phoned me and I discussed my problem with him on the 15th March 2018. He said the problem was escalated. NOBODY PHONED ME BACK!. I then filled in the online complaint form again. NOBODY HAS PHONED ME BACK. Service is absolutely terrible! Why do they not phone back or fix the problem? Really thinking of going elsewhere. Why have an online complaint form when no-one takes any interest in it.
