Terrible service, no care and concern for valued customers

In August 2025, I bought 1kg Kashmiri extra special masala. I only only it in the beginning of Sep 2025, when I discovered that the masala gave the curries a distinct sour taste. At first I thought it was just me, then used it again to cook another curry and discovered the same sour taste. I called Gorimas Sandton to explain my issue and was told that someone will call me the following Tuesday. To date, no call back, it's been 3 weeks. Also the person refused for me to bring in the masala so they can test it and said must wait for someone to call me. I explained that Sandton is out of the way but I had time that weekend to drop it off, she refused. I also advised that I usually buy from Gorimas at the Glen and never had a problem. I am so heartsore that Gorimas Sandton couldn't care less for a customer who has been purchasing from them for over 7 years now. So disappointing. They didn't have the decency to call me or even offer a replacement for the masala.
