Clicks: feel bad, pay more!

I had a very disappointing experience at the Tygervalley branch on Sunday 10/10. I had bought a Sorbet Age Perfect Eye & Lip Serum on a 3 for 2 special on 27/09. I bought it because of the special, despite having some at the time. When I opened it last week I found that it was very runny so I took it back to the store, where I was interrogated as to why I hadn't used it sooner. The cashier left me for 10 mins and returned with the skincare person. There was no mention of the quality of the product nor whether there was any merit to my complaint, rather I was made to feel like I had done something wrong. How dare I expect to exchange it for one that was not runny and I had become accustomed to. I was summarily dismissed, with an audience eagerly watching this unfold, also chastising me with their eyes for holding the queue up. I felt humiliated and infuriated at the same time. The expiry date on the product is 07/2022. the bottom line is it was a defective product! I sent them an email and have had absolutely no response.
