Monginis Cake — bar cake was overbaked with no taste

I had purchased a bar cake of fruit flavor from a shop in Vapi, Gujarat (batch no. DM3722; date of manufacturing- 11/05/2018). The cake was so overbaked that it had lost its fruit flavor (in fact bitter in taste). Initially I thought I had mistakenly bought chocolate flavor but the brownish black color was due to overbaking of the cake. This had happened second time. Now will rethink before buying/recommending Monginis bar cake. Request to please improve baking and making quality.
