Pick n Pay Bottles

Used the PnP Bottles application for the first time over the weekend. Order and payment was for R4,100. On the day of delivery 4 additional amounts were deducted from my credit card and payment in total was for R6,500. Invoice on the app still reflects as R4,100 and I still have no idea what the additional charges were for. After 35 messages and 28 calls I have now asked the bank to dispute the additional charges. Really disappointed in both PnP and whoever created the app.
