Express Appliance Repair In Winnipeg

Back in April the settings on my stove timer weren't working and the timer would go off every hour or so. I called Express repair to come take a look. In my phone call, I specifically said what the issue was and asked for a quote, which they did not provide. The only thing they said was that it was a $99 service call to assess, and if I wanted it repaired they would credit the $99 from the bill. When the Tec got to my place he pressed a couple of buttons and the settings didn't work for him either, so he looked up the part on line and said that the parts were obsolete and he couldn't fix the timer. I was disappointed that they couldn't fix my stove ( I was left with a beeping timer) so I asked if he could at least disconnect the wire to stop the beeping. The tec said it would cost me $290 ( this is already with the $99 deducted. I was floored and said " TO disconnect a wire?? And not fix my stove??". He didn't say much other than that's a flat rate....In frustration and needing the beeping sound to go away, I said yes, all while feeling I am being exploited. After the Tec left, I called customer service to complain and they were rude, and dismissed me saying he touched my stove so the charges applies...Obviously he touched my stove, you can't assess without touching, but he didn't fix anything, I still have a stove with no timer. I requested to speak to Management to which I was told they were gone for the day. I asked if they can call me when they are back, I never heard from them. I called again a few days later and they weren't available. I asked if they could call me back. To this day I am still waiting to hear from them...To add insult to injury today they texted me saying that they "validate" me as a customer and would like to offer me $50 off my next repair, to give them a call to schedule an appointment...I don't want to deal with them again!! I don't want $50 off my next repair, I want a refund no strings attached!
