Standard bank and zestlife worst health broker

I was contacted by Raeez Folletine from Zestlife on behalf of Standard bank to offer me a personalised broker service for my Medical Aid. He was quick to respond when signing up and offering me gap cover etc. When I traveled outside of SA recently i needed a letter from Discovery Medical Aid and i sent Raeez an email before we left and never received a response. I am now on my last day outside of SA and still have not received a response. This is exactly the type of service i expected from Standard Bank and anyone connected to them but like an idiot i thought this would different. Truly ridiculously poor service from everyone involved
