Devil's Peak Brewery - Retail via Takealot

My wife purchased a Devis's Peak Lager 5L Keg. (Ref. 58742033) - Return request (MRRN-RZD8R-NOAK) I opened the Keg and poured ONE (1) glass from the Keg. This is not the first time a purchased a similar product and therefor knew what I can expect. This ONE (1) glass was good. When I wanted to pour a second glass shortly thereafter the beer was flat and without any carbonization. The Keg was opened and used as per the instructions on the Keg. As much as I am aware that Takealot does not accept returns as per their website for Alcohol, this obviously indicated the item was defective. This is a poor reflection on Takealot as well as Devil's Peak Brewery. It also contravenes the CPA as there is an imp**** warranty on ALL items, you cannot choose as a business which items you guarantee the quality of and which ones you want to exclude. If this cannot be resolved, I would urge anyone to seriously reconsider purchasing this spesific product as well as ANY product from Takealot as I do see their policy on returns for DEFECTIVE products as questionable.
