Hirsch shocking service as usual!

I have been trying to get my AEG fridge repaired under warranty since the 13th of May 2019, after numerous promises to get it attended to, three call outs from various repair service providers appointed by AEG and Hirsch, to date it has still not been repaired! This is utterly disgusting that nearly three months later I am still waiting! Not sure what to do anymore as between Hirsch and AEG it appears they are both as useless as each other!
