Poor quality clothing

When lockdown regulations were first eased and shops could sell Winter stuff, I went pass Ackermans Lalucia, and got my son his morning shoes, so he can be warm when he gets out of bed. He is 2 years old. The shoes lasted a month, bear in mind, he only wore them indoors. When I lodged a complaint, no one responded to it. I did it again in the last two weeks and still no response. The quality of their clothes is ridiculously low, whereas their prices are getting more expensive. I am really disappointed and really need an answer.
