A little slow to complete- but very competitive price.

Did this for Marvel Rivals boosting, I've used these services before in other games and generally get same day turnaround- but normally x3 the price.

This seemed a little too good to be true, but thought I could try it.
Did get a response in about 30 minutes of the order, first person they assigned me to did not respond until late in the night, to which they automatically moved me to someone else who responded pretty much instantly. Took about 3 days to complete, as the booster said they had a lot of throwers/issues in their games and they were playing the full time.
But all my requirements were met and my rank was achieved. :)
