bad response after lodging a complain

Went to spar to buy cake and the lady told me that the cheese cake is hard because of the temperature of their fridge, OK fine I accepted and then came back to buy a black forest and another lady different from the first one told me the same thing that the cake is hard and then went to ask the manager to fix the problem but instead it turned into a scene and a prolonged talk with defensive attitude that there's no such that the cakes are hard and why am I the first person to complain whereas they've got thousands of customers coming to buy those cakes so I then told him since he's fails to help me I'll forward the complain to hello Peter and he asked me who is that? And my response was he'll soon find out and when I got home to even taste the cake it was so hard and tasted bad, since spar is well known to have the best bakery I was even more dissatisfied by the taste of their cheesecake the standard has really dropped the manager (Harry) didn't even have the courtesy of saying we sorry for the inconvenience but instead tried to make me look stupid and interrogated me and even tried to intimidate me in a way
