No aftersales service

I had my pool fiberglass by Richard and his team from Fiberglass Pool Repair in Augsut of 2024..He is very active on Tiktok and had lots of good reviews and videos of pools he had completed. I paid a 70% deposit and work began and was finished after 2 weeks. A month after the completion I noticed a whole the size of a R10 note. I contacted him on numerous occasions to come and fix the hole.Loads of Whatsapps,missed calls, false promises and almost a year later-nothing. He is still on TikTok selling. Also no address on invoices or names to try and investigate.
