UNHAPPY ☹️

I bought a bottle of Hennessy from Tops Jean Avenue on 27.09.2019 for my brothers birthday he saved it and waited to opened it for an occasion- he opened it on 24.12.2019 and the alcohol is off! It smells terrible and tastes disgusting. We took it back to Tops Jean Avenue and they said they want to investigate - I’m not sure exactly what they want to investigate. I believe this was old stock or spoiled stock and we always buy Hennessy. Extremely disappointed. I also have my bank statement that shows the day I bought it. We took the bottle back to Tops at Jean Avenue and still waiting a response
