Faulty microwave from the store game an sumsung supplier

I bought a microwave at gave store Vincent Eastlondon on the 22 October 2024 in March 2025 microwave stopped working I took it back to the store I was told it’s gonna be taken for repairs 2 weeks later I went to check on microwave was still not fixed, on 28 March I recieved a call saying that they can not fix my microwave cause they found ****roaches 🪳 inside so in longer under warranty or garantee so my question is where do the ****roaches come from cause I don’t have that in my house or is that a way of game or sumsung are using to **** poor people I’m annoyed and disgusted 🤢 by this level of service microwave did not last even 6 months
