Customer service failure to recognise, repair or replace integrated fridge Ref BJ160766

November 2018 I purchased all new Siemens appliance for I house I was in the process of completing in order to secure the price before the increase in Jan 2019. Appliances were delivered and installed Jan / Feb 2019 and I moved into my new home 28 Feb 2019 within a couple of months I noticed the integrated fridge bottom vegetable drawer froze the vegetables that were placed in the "back" of the drawer. When I called the Sales man about this he said it's because I store my product in the plastic wrapping it is purchased in - so take them out of the packet? Really? Take your fresh carrots that you bought from Woolies and store them loose in the bottom drawer? Take your convenience cut mix veg out of the packet and store them loose in the bottom drawer? This complaint was registered many times, the technician came and so the problem continued. In sheer desperation 10 Feb 2020 I called again and was less patient with the customer service representative as I asked to speak to the service manager. She promised to help me and the lady who overseas the call centre called me back. She arranged for technician to put in a temp logger that same week for a few days and it was then removed. Then noting. Vegetables continue to freeze in the bottom drawer, so again I call on 25 Feb and leave a message for the service manager to call me. Todate still nothing. Then again today I call and ask for the service manager or technical mgr to call me still nothing. Customer service lady said she would look into this and get back to me....Good news she has come back to me tells me she has sourced a PC board for me and a technician will install it tomorrow Friday 28 Feb 2020. I did mention to her that no confirmation was required to confirm the call for Friday 28 Feb. I also advised her that my complaint was going to be made public on Hello Peter. Lets see if my complaint is finally attended to? The last service call ref I have for Siemens is BJ160766
