eNOM verzus InterServer 2020

num reseller in the past you had to pay $1,500 so I had PAID to be a platinum reseller)
Despite there being much cheaper alternatives to Enom for .com domains (EG: NameCheap, Godaddy, ResellerClub), I have alway stuck with Enom throughout the years.
I was then "thanked" for that loyalty by receiving an email on the 1st of May 2018 saying that my prices for .com domains will be increased 35% + on the 30th of May, not even a months notice.
Reference: https://help.enom.com/hc/en-us/articles/360002746672?input_string=complaint+from+loyal+client+regarding+the+35+price+increase+coming+in+at+the+end+of+this+month.
The reason for the increase given in the email is that they will be implementing "significant changes" to their pricing model in an effort to establish more transparent pricing and reward resellers for high volume and growth. The irony in that statement is that whilst they consider it an "effort to provide transparence and reward", my impression is that they are trying to squeeze profits but disguise this with marketing jargon. Its literally a scene from Dilbert!
For example, I was paying $9.98 for .com domains and according to the notification, at the end of May this is increased to $13.50.
I have 350 domains so this increase takes over $1,000 a year DIRECTLY from my pocket and gives it, as PURE PROFIT to Enom which would not be absurd but for the fact that Enom is now owned by Tucows who offer their resellers .com domains for $12.
The sad thing is, that the only option I have would be to transfer the domains to someone like Godaddy who offer their .com domains for $8.95 or NameCheap who offer their domains for $9.92 but this of course require a significant amount of works and cost to me so there is not much I can do as you have me over a barrel as the saying goes and Enom knows it.
I appreciate a company has to make money but I think pushing aside those people that helped build that company is not very good form at all. Even google would not do something like that!
At the very least I would have expected my prices to be grandfathered in rather than being told that I need to pay an extra $1,000 a year for my domains starting within 30 days.
Really disgusting company.
!!!!!AVOID AT ALL COSTS!!!!!
