Very bad service

Not very happy with the service i am getting. Get plumbers to fix a pipe in my wall. Had to get them back 3 times to correct the repairs. Nobody followed up. Waited for tilling to be done. They tel me the contractor is approved after i am waiting almost 2 weeks i tel them to pay the money they say they need to find out with the contractor if he bought anything. When i spoke to the contractor he says he is waiting for approval. So to fix something in my wall im waiting 2 months now to bath again. Not acceptable.
