Service not great additional extra charges

ASAP! Hi I am appalled at the service from customer service.I have asked about additional billing and this is the second time this has happened.I was enquiring about what the additional R24.80 was for. I was charged R84.99 for the chicken and then additional R24.80 for packet that was R33.40 on the parcel.I was charged for a Canderel Bubble chocolate and never received it.
