Disappointed in Blum’s willingness to help

I had a kitchen installed 12yrs ago with Blum cupboard fittings. Fancy & very nice. But with age draws fronts are dropping & not pulling in. I contacted Blum & was given technicians number & email. I emailed on everything twice, called in between to pls get the technician to respond. About 5 wks later after hearing nothing i called again very annoyed with the service. Spoke to manager who also said he would come back to me which he didn’t. I called again & said got no response & then got a WhatsApp saying there was a email (which i never got) & they dont do repairs. Surely it’s a service they could offer once the kitchen people are no longer around. They know their product & it’s a simple fix when you have the right part. On top of it it’s not like they have to travel far, i am down the road. I am very very disappointed with the service or non service & the slack slow reply. One expects more from a German product. I was told to find a carpenter!!!
