Monginis Cake — Bad quality cake

I have had extremely bad experience at Monginis Baner Road store. I had told my sister to get proper cash memo, because I know this store over-charges. Even after asking three times, the store did not give proper cash memo. They gave "order memo". They did not even put the date on it. When I complained, the shopkeeper said "Do whatever you want" and "I am sparing you just because you are a woman." They are supposed to give proper cash memo. I have all documentary evidence and record of phone call. The cakes itself are of sub-standard quality. It is not sponge cake. It is completely dry cake layered with "cream" but the "cream" is horrible. They avoid putting date because cakes are not fresh.
