KFC - R5 for 6 grams more chips (The difference between Regular and Large Chips)

KFC is really down the tubes.....quality of the meal, service, even their customer service call center is a waste of time. Purchased meals and chips on the 29 August 2020. Regular chips and Large chips, was roughly the same quantity....merely 6 gram difference, yes I weighed them and have photo proof. Needless to say, the contact center tries to contact me 2/09/2020....I answer, the line is silent...call is dropped, 30 minutes later I receive a message, saying that they tried contacting me and will try again in 24hours, if they fail the case will be closed. I called them up on the 03/09, after not receiving a further call.....the agent advised that they they will be in touch - 72 hours later, I get a call....(06/09) - same story, they try calling me and I answer and no response. So I decide to call the contact center on the 07/09....after the usual "Sorry".....the case is to be referred to management.....You have lost me as customer and really I don't think I'll be missing out - if this is the poor service and quality you provide
