Hello, I purchase a cake from near kaspata vasti Monjinish store, Pune yesterday on the date of 1st may2016. It is tottly unhealthy n too much hard . The cake was spoiled my birthday so what can i do plz inform me...and when I called the they said bring it back will exchange it and they need that old cake for tasting .when I send that cake the owner said it's OK and it's fresh cream and the taste will be like that and talk very rudely .it's really a bad experience.
