DRIP Order with Questrade

I just noticed a problem with my DRIP order in my Questrade account. The executed price shown in my webtrader account is different than the one shown in its backend system Penson. The net difference is 2%!! They are not sure what is going on now, but will e-mail me back when they figure it out! I will sure not be letting this go without a proper reply. Let's see what they come up with.
