Whizzer poor quality and poor customer service

My cousin and I went to the Chatsworth branch milky lane as we always eat at this place every week. Sometimes my family and I go three times a week. We ordered a waffle and the peppermint whizzer. The peppermint whizzer was extremely unsatisfactory as the chocolate was stail and didn't even taste like the aero peppermint chocolate. The ice cream wasn't mixed well and was bare and plain. We told the waiter about it and they took it back. The manager's response was that the whizzer was coloured however it tasted horrible compared to buying a whizzer from another branch of milky lane like suncoast. Eventually they took the whizzer and offered us to take away.not even offered a new ice cream and we were still charged the full price of R35 for the whizzer which was not eaten. Due to this, no one from our family or friends will be supporting this branch milky lane again due to their poor customer service delivery. I would rather support spur that sells quiet good waffles and other ice cream outlets.
