Poor customer service and terrible, ********* service probiders

I was attacked and verbally abused by your service provider after he bumbed my gate as he was coming in. I logged a claim for a burst gyser with jaunita and he sent Plumbing Mecca Boksburg. They call and we made arrangements for them to come at 2pm. 12pm I received a call frm them saying they r by my house. I told them we arranged for 2pm so I will only get there that time as I was at work. When I finally arrived I found 2 vans one parked on the side and the other on my drive way. I then hooted for them to make way. He reversed I got in then and was about to park my car in the garage. As I looked back I see one of the vans followed and bumbed my gate. The car got stuck on the gate and the gate was damaged and stopped working. I asked them who let them in and I needed to closed up for the dogs before I let them in. There was 5 men and the other one started shouting and rudely asking for proof of payment before commencing. I can not explain the manner in which he was aggressive and now claiming I bumbed his car and that he has no time for my nonsense. He became so aggressive that I was terrified having 5 men in my house that I don't know, who looked very doggy and gangster and me being the only female I was honestly in fear. I called the contractor who also was not helpful as the guy was shouting and making a noise.they left my gate no working then I called the insurance agoin to tell them what happened. The lady was helpful and got someone as I was in terrible state and traumatised. Got another plumber to come through and sort out my geyser. They came following day but the gyser was big and they had to cut up a bigger while. Gyser finally fitted but now I'm left with a dirty walls where rusted water ran from the gyser, ceiling not fixed and no feedback. My gate is not working. Do you check or ensure the people you send out are credible and do the right job. Not just that are they ethical. As I pay to get good service and also have piece of mind and be safe. I feel momentum only cares about collecting premiums and don't check on who they send out to people as I complained nobody cares
