Claim not sorted after 4 months

In October 2014 I had a lightning strike at home that fried many systems and appliances. Nedbank Homeowners insurance appointed Mr Technology as the supplier to repair / replace our alarm, gate motor etc. They never did however replace the key pad at our gate. I have called both the supplier and Nedbank Insurance many times. The Nedbank representative (claims manager) confirmed that Mr Technology had been paid for the replacement of the unit, and they would follow up. I was promised a call back several weeks ago, but have not received any call, nor resolution. I just tried to call both Mr Technology and the Nedbank Insurance call centre - but luckily for them, they only work until 16h30. Please can someone who can resolve this for me kindly get some action on this - its not difficult and I'm very frustrated.
