Starline Windows

I had a lot of windows installed through Starline probably 20+ windows in all, most where OK although there were a few products that weren't exact or were installed slightly at an angle. Then I had the glass repaired as a window broke which costs about $170. I'm not great at checking VISA charges monthly as my bill is online and I usually just pay it, but I did check this time because the amount was so high because by "accident" they charged me an extra $2500!!!! It was apparently a mistake. They barely apologized. There was another confusion about a bill and they couldn't explain it to me and treated me really rudely. I'd say it's all good with Starline until it's not good and something goes wrong and then the customer service is abysmal.
