MRM Electrical caused dead short on my DV board

On Sunday, 27 September 2020 I contacted Standard Bank's home insurance Home Assist line in connection with a problem we were experiencing with our plugs tripping. On Monday morning, 28 September 2020, two technicians from MRM electrical arrived follownig this home assistance call. I explained the tripping problem we had experienced the day before and they immediately opened the DV board to look at what was going on. Instead of investigating whether any of our appliances was causing the problem (which was the case - as we discovered later, the cord of one of our appliances had gotten caught in a toaster) these two technicians from MRM elctrical proceeded to UNEARTH our gesyers, fridge, swimming pool pump and (as it turned out) a number of plugs. I was concerned but they assured me this would not cause a situation of electrical non-compliance. After they left, I discovered that my stove and geyser were still tripping. I called MRM electrical back, but after waiting for hours for them to arrive asked them to come the next morning. When the technicians were late again, I called in a different electrical contractor. He was able to fix the stove issue but discovered that MRM Electrical technicians had caused a dead short in the system WHICH HAS STILL NOT BEEN RESOLVED. This company needs to be taken off SA Home Insurance Home Assistance database immediately and their licence to operat must be revoked.
