I've experienced that too with Youtube SEO-related services. They tend to start A LOT later than normal/scheduled. This is the biggest disadvantage. Although I can confirm that when the service (not this particular SMM Panel) actually works, it does a good job generating CTR/Impressions. However, getting an order to go through + its price is the biggest problem.
I tried another SMM Panel with a similar service but it still didn't start. I did try this for like a few months ago and it worked. The main issue really is the order processing. If it works, it works very well as it does indeed generate impressions/ctr. Here's a pic of one of my videos that ordered like 2k of these.

Notice how in this chart when I ordered it, the impressions counter went up by almost 1k and the click-through went to almost 40%? Sadly these services don't always work but when working, it is a godsend.
To add onto this, I'm gonna test another SMM Panel for SEO Youtube views. And I'll let you know if it works or not.
Does that service even offer views that generate impressions/click-throughs?
