Poor service from Momentum and their service providers

I called Momentum assist to ask for a plumber to be sent out to assist with a leaking water pipe. Designer Plus was despatched to attend to the repair. The plumbers were very unprofessional and *********** and struggled to carry out a simple repair. I doubt that the plumber sent is even a qualified plumber. After expressing them my dissatisfaction with the shoddy workmanship they assured me that there were no leaks and the problem was sorted out. I had to pay them R200 for the work carried out. I noticed after a short while after they left that the section that had been repaired was now leaking at the joints. Someone tried to contact me from Momentum and I tried to explain about the poor quality of the job but they said they could not hear me due to a bad line. They did not try to even call me back. I tried calling back the same number but it does not work. I then tried calling Momentum Assist to report the issue and was further frustrated because the agent said he could not pick me up on the system even though I had just registered a claim earlier. I have also been a policyholder with Momentum for many years. Eventually when I did speak to a supervisor to advise him that I will be getting my own plumber to carry out the repair as it was a leak on the main water line entering my property all he could say was that he could not authorise me getting my own plumber and he would need to escalate this to the same service provider who may be able to send another team out. He then proceeded to ask me for my email address. As long-standing customer of Momentum in a time of crisis getting asked for my email address is very frustrating as I had just registered a claim. According to him Momentum assist does not have access to my details. How did I register a claim earlier if Momentum assist has no access to my details? Are you not able to pick up my email address from the policies I hold with you? The level of incompetence from the original providers does not give me the confidence in getting anyone else from that same company out again to mess up this any further. As this is a leak on my main water line entering my property I have already arranged for another plumber to carry out the repair asap. It is sad in an emergency to have to deal with an *********** service provider sent out by your insurance company. Then having to deal with *********** call center agents who say they can't pick you up on the system because you gave them the incorrect surname. These should be people that can listen carefully and work accurately. I'm utterly disappointed with my experience with Momentum today and would like to think in a case like this where there is an emergency and something critical needs to be repaired immediately by people qualified for the job that service providers sent out by your insurer are competent and screened that you don't have to go get someone else to redo their botched job. This is clearly not the case.
