Refusal within seconds

regular customer<br> <br> So gutted by the bad service I received at Durbell Pharmacy Cape Gate. On Monday the 08/06/15, I bought a consumable item with the help and advice of 2 shop assistance. Afterwards before using the item I did some additional research only to found that I had the right brand in exactly the same packaging but the wrong item, I then only went to exchange the item on Wednesday 10/06/15. On my arrival I went to see if the item I want was there and indeed it was there, packed to capacity (both items) and I also happen to see one of the assistance that assisted me when I bought the wrong item on Monday. The assistant then took me to the Pharmacist (Johan van Rensburg) to authorise the exchange. It took Mr van Rensburg less then a minute to refuse my exchange because according to him my returned item's packaging was not good enough to which I totally disagree. Mr van Rensburg had an unwelcome attitude and me not being one for arguing I just ask for Johan's name and bearing in mind there's sites likes this that can look into the matter. I'm sitting now with something I bought but which I can not use and meanwhile I will no longer use Durbell as my first choice pharmacy.
