Tekkie Town lack after sales service

I bought a pair of CAT shoes from Tekkie Town. This is not the first pair that I have bought, as they are good shoes. However, the shoe laces on one of my pairs of shoes broke. Tekkie Town was not interested in helping me, or couldn't, which is not good after-sales service at all. After following up with them numerous times, they eventually gave me their supplier's number. The supplier also wasn't able to assist me. I ask, how can shoes be sold when there are simply no replacement shoelaces available for these shoes? Shouldn't that be a basic requirement? Nobody else from different shops was able to assist me either. I went to about 7 different store brands.
