No response and call cut off

I called on Saturday morning, 24th Feb 2024. I explained that my oven door glass had shattered, and that I needed to replace it. I was told that they would phone Defy first thing on Monday and obtain a price for replacing it. I phoned on Monday at 2:55 pm and was put through to Spares. It rang for a while, and then this American voice tells me they cannot find the person I am looking for (and there was no specific person, I was just waiting for Spares to answer) and the call was killed. Well, I'll never contact them again, I'll call Defy and purchase fit the door myself. This company is useless.
