No After Sales Service

I have been attempting to replace the shoelaces for a pair of my CAT shoes, purchased at Tekkie Town. My shoes are still in very good condition. Firstly, Tekkie Town was totally not interested in assisting me. However, after contacting them on numerous occasions, they did eventually give me the number of their supplier. This whole exercise has been going on for at least a month. Now they simply tell me that they can't assist me. Very frustrating.
