Herbal Cough Syrup

Good Day

I purchased Medirite Pharmacy Herbal Cough Syrup. I'm completely dissatisfied with the product as it is not up to standard. The mixture split and is grainy and gross. Can I please have my money back; this is a horrible product. The expiry date is 08/2022 (BN:20 J 208; NAPPI code: ***).
