Bakers biscuits and its bad service

I purchased a few items which had i left a message on messenger with regards to the quality so i get called i spoke to two ladies that asked me questions about the products after answering the questions the lady called me bk few days later saying they would be sending someone to fetch items so i sent the items with ram couriers its now almost 3 weeks and i havnt got a call bk i also purchased fishfingers and big korn bites which i was told that i cannot be reimbursed for because i dont have the packaging and contents how would i have the fishfingers on hand when i had fried them and these people called me a week after a lodged a complaint so was i suppose to keep that defective cooked product and the big korn bites was expired i sent through pics but i still wasnt reimbursed so probably will have to change brands why must i support a business that doesnt care about customer satisfaction
