Extended warranty - Dishwasher

We bought a dishwasher on the 6 April 2015 , Makro Centurion was quick in selling us a 5 year extender warranty , on the 24th of April 2019, the Dishwasher stop working and a burning smell start coming from the Dishwasher, on the papers a policy number trough Mutual and federal policy 123403 was stated, phoning Mutual and Federal they know nothing about the policy, My wife gone to Makro Centurion to find out what is going on as the 5 years was still not over, they told her not to worry and they will send technicians to fix the dishwasher and if the technicians can not fix it the dishwasher will be replaced. After many calls the technicians did arrive late and with all sorts of excuses, They find out that the outlet pump had a leak to a wire and this is causing the smell as it is burning ( in my view this could cause our house to burn down) they promise that they will have to find out what the price of a new pump is and then Makro Centurion have to decide if they are going to fix it or replace it, On 2nd May 2019(more than a week later) after not hearing from them , My wife gone back to Makro Centurion , only to found out that they do not know anything about this.

I do find this absolutely uneatable, the service is really bad.
