HORRIBLE SERVICE

In july 2017 I bought a box pinacolada at pnp liquor in paarl for ,R100 ,open the box and the content inside the bag was water,I then went back to the store the cashier phoned the store man and he did not answer,she then give me another box and took my details then I left, about a half an hour later the store manager came to my workplace saying that I should pay for the second box and that what im doing is ***** and the he can put me in jail keep in mind this is the store manager,I told he how in the hell im I suppose to put water in a sealed bag he answer he dont know, I then give him the R100 caues he said hes gonna short this out and he didn't. On these dates I phoned customer care 6 sep 2017, 5 oct 2017, 3 nov 2017 and all this calls they were gonna escalate I dont know to where but didn't hear back from no one I phoned again to customer care on 30 may 2018 and asked to speak to a supervisor and I got Dessery I then told her everything and she said shes gonna phone the store an will get back to me that day or the next up until now no one phones me back and I want my money back and this is HORRIBLE service from both the store manager and the customer care people.
