SIEMENS NO AFTER SERVICE

We logged a complaint on 29 April 2019 about our 137 Siemens Prata mattress, with springs coming out on both sides of the mattress. We eventually got the person to come out to quote us, as it is under warranty, he came out on 15 May 2019 after I had to go back and ask for his number, I had to phone him. I have to follow up from my side all the time, today is 5 June and still no quote. Yesterday I mailed again to ask for any feedback without any reply. On 24 May he rep**** " I have submitted the matter to the factory and am still awaiting a response. I will follow up on Monday again. (wonder which Monday he is talking about). Never heard of this guy again. My bed is 7 years old, 2nd replacement (so actually 4years old) the springs coming out again on both sides of the mattress. I will NEVER EVER buy anything from Siemens as there is NO after service at all. Why must I the client keep on following up? 29 April to 5 June 2019 and nothing yet. Please think twice before purchasing from a place that does not have an after service.
