Bad Service - Work with no Guarantee

Me again. Work was done last year in April/May 2024. We noticed that sand and debris started falling out of the mixer fitting, we took photo and sent it to Antz Plumbing. We got a response that they will send someone to sort it out. All of the silicon came off from around the bath tub, that has now "settled" and this also needs to be re-done. but guess what? The OWNER responded that they cannot do anything as time has "expired". I asked what were their terms for guarantee on job, and didnt get any response. I contacted another Plumbing company and they said that Antz Plumbing did not do a stellar job for the sealant to disintegrate in the mixer, which is why plaster sand is coming off the wall, and that the silicone was also not app**** proffessionally. For R14500.00 to replace the bath tub, basin and toilet, ANTZ PLUMBING is the worst to deal with. The previous owner will be so disappointed to hear how his business finally turned out. These people need to find a new name for themselves and not run on the coat tails and recommendations of the previous Owner who was a professional businessman. Please do not use ANTZ PLUMBING and ELECTRICAL for your plumbing needs. These people will overcharge you and leave you out to dry when their shoddy work comes up. I have to now get a new Plumbing company to come and fix their mess!!!!
