Not good for my scalping startegy

I've been scalping Pepperstone for a few months and have had a terrible experience so far. I am having trouble executing orders as the server response is very slow and my strategy target price to entering the market is useless. And because of that, dont expect to gain profit with that order execution condition. So, I wrote to them and you know they said a system error! I am thinking of only me trade with loss because of system bugs, and yet they don't do anything about it. So instead of complaining all the time, I think I will switch to another platform as soon as possible.
