Bad service

I reported my faulty geyser on 08 June 2020 to FNB Insurance and was informed by my insurer that I will be contacted by a plumbing company on 09/06/2020. On 10 June I called FNB again indicating that I was still waiting to be contacted only to be called on Wednesday by Simply First Plumbing telling me their workers will be out on Thursday between 3 - 4pm They arrived and replaced the element and thermostat which is still not working. I called the office this morning requesting they come out early this morning and got an attitude and was told they will be here after 4pm. This is not acceptable and I want Old Mutual to contact them as their service is pathetic. They can refund me and remove their element and I will contact a plumber in my own personal capacity. I want the payment made to them reversed. Please contact me as I have emailed and fnb credit card
