Poor service and lack of customer care!

Lack of service and care! I have been sent from pillar to post for the last month regarding a refund on 2 sets of netball bibs I bought from them. When the 2 sets arrived 1 bib was missing, so they collected the set and sent me a new set. After the first wash the bibs had holes in them and the positions started to come off so I booked both sets for return and asked for a refund. I received a refund for 1 set. I have been sending emails daily for the last month. Once I supply all proof that only 1 refund was received on 1 set, I get ignored until I send another complaint and then get in touch with a new agent who asks for all the proof all over again, just to ignore me once again after I supply all info. They should just check their bank info to see whether there was 1 or 2 refunds made. At my wits end honestly! This money belongs to a netball club and new bibs needs to be bought. I'm hoping someone will get in touch with me via this post, as this is my last resort.
