Airsoft Canada - Broken charger TORONTO AIRSOFT

So about a month ago I went into Toronto airsoft planing to buy a 9.6 nun chuck battery, my m4 is wired to the front so I would need a peq box to hold the battery, after trying to make the battery fit it was a no go... After the sales person started talking to me he turned me to a small 11.1v 1300 lipo battery and advised to buy the most expensive charger they sell and kept pushing on it so I agreed, now 75$ charger 35$ lipo 35$ peq box I ask him for sure will this battery work with this charger, sales person says yes he has the same charger.
Upon arriving home I plan to storage charge the battery, and put it away as I won't be playing for a month because I haven't yet purchased all my gear. Get home the battery has tamia connectors and and the charger does not. only has deans and a couple other so now I can't charge the battery or storage charge it, the sales person advised me as soon as I get home storage charge it before storing the for over a month. This was on a Sunday. They don't open till wends day worried that the battery will have damaged cells do to them fully charging it in the store, I have the battery and my gun wired to deans, the next day. I storage charged the battery, it did this in under 5 minutes, I have yet to touch the charger for a month, finally my first game, I go to balance charge the battery, the charger is charging to 12.3v when the battery is rated at 11.1v the charger got extreamly hot then read input volt error. I set it to 11.1v 1.3a balance charge. Now went into select paintball/airsoft they try a few battery's and there smart charger and inform me that the charger is broken. Something internal isn't functioning. Now with a fried charger I call TA EXPLAINED TO THEM THE PROBLEM the sales person on the phone said we can't help you bring it in we will look at it and "mabe" give you a very small discount on a new charger, I asked to speak with frank or a manager. I was told they won't help you.
I recived a broken 80$ charger that was pushed on me in the first place by a sales person, all I want is at least an exchange. I have messaged karnage without a response.
I have spent over 1000$ there in the last 2 months, I think I should recive at least some kind of an exchange.
