Awful service and workmanship

Absolute plumbers were subcontracted to re-grout my bathroom and the service and work was very unprofessional. After booking them in for a certain day at a specific time, they didn't arrive. I made endless calls and had numerous excuses from them. The job was then re-scheduled for the following day at 8.30am. The work men only arrived at around 11.30am. (They had to catch the train from Claremont to Simon's Town). The job was finally done. I was quoted for having the shower floor re-grouted, but while the grouters were there they grouted areas on the walls. The grout on the floor was a grey and the walls off white. It does not look good. I admit I said to the guys it would be good if they could do parts of the wall. But if they are supposedly professional they would have told me it would have been a different colour. I was told the grout would lighten which it hasn't. I have communicated this to OnCall CTM on numerous occassions and have had no response. They are not interested. Stay away from this company!!!
