Compliant

I bought a cross and Blackwell tangy mayonnaise bottle. As I was close to finishing the bottle found a piece of glass. Called the shop where I bought the mayonnaise and was advised to call the company that made the mayonnaise. Called tiger brand. Spoke to a lady and she requested for evidence. Sent her an email with all pictures she requested for. Last month. Till today. Still no reply to my email or call or any sort of feedback.
