TFG group mislead people with false vouchers information.

I opened an account at Jet Greenacres Port Elizabeth few weeks ago. There is a big banner outside that says you get vouchers if you open an account. I was informed I will get an sms with my vouchers but to date no sms yet. I phoned the call centre then a lady from Jet phoned me and assured me I will get my vouchers. Then got sms that my complaint was resolved. Phoned again they said I will get it but still nothing. Phoned again spoke to a guy who said that it was unacceptable for me to receive such service and he will personally take responsibility, he will phone the branch and get back to me the same day. That was last week has not phoned me back. They mislead people by saying you will get R1500 vouchers to open account but you dont get it.
