Arçelik Sold Me a Faulty Dishwasher That Leaks and Builds Up Foam After Use

I wish I had never bought anything from the Arçelik brand—this has been my worst experience ever. When we ran the product for the first time, foam accumulated at the end of the cycle. On top of that, when we filled the rinse aid compartment, it started leaking. Despite it being our first use, the product turned out to be faulty. We requested a return and have been waiting for a week, only to find out that our request was rejected. They said a service technician would be assigned and the product would be inspected, but no one has contacted us so far. This situation is deeply upsetting and completely unacceptable.
