High ping

Hello, I play FIFA competitively and I'm having irregular ping issues. It will randomly spike quite high, but it ranges anywhere from 28-36ms. Ping this high creates input delay while I play and can effect the outcome of situations, in turn effecting the outcome of matches. I've been looking at message boards and there seem to be a number of people having or had similar issues. I've ran through all the troubleshooting recommended, with no improvement. This is sort of driving me crazy and need help by someone who knows what they're talking about. I've called in a few times and I'm told everything looks good on their end. It would be so much appreciated if someone could dive into this deeper.
