Again shocking service Standard bank

In last year I informed standard bank of a possible leak in my ensuite The plumber came through to do a leak detection test and I was advised that there was no leak. They said it was my shower head I contested this as there was water on my floor But I left it as they were the experts The leak got worse as the damp behind my hand basin was very bad. I once again contacted std bank and the same plumbers arrived and this time they detected the leak and replaced the pipe. When the builder came to repair the tiles he told me to get hold of the plumbers as the entire wall was wet. So I did.this and now I have been informed that Mr Weidemann has stopped further repairs as this will be the third pipe replacement Please note that only 1 pipe has been replaced. No one has contacted me from Standard bank No assessor has come through to see the damages and now I am being told that as I have had 2 pipes replaced already which is not correct that the cost is for my account. Shocking communication in fact No communucation at all as I had to deal with the call centre to try and find out why the plumber had not arrived. 1 week no shower
