They did, but it wasn't particularly clear.

Thank you for contacting ICANN Global Support.
I apologize for the difficulties you are experiencing. Unfortunately, ICANN does not control the sale or pricing of domain names. Registry operators and registrars are free to charge a premium for certain names at their discretion, assuming they are otherwise in compliance with the terms and conditions of their agreements. You may refer to the registrar's domain registration agreement to identify what the specified rates and restrictions are.
A registry operator or registrar may not implement/impose abusive or discriminatory renewal pricing practices without the written consent of the applicable registrant at the time of initial registration. This includes, for example, the requirement for advance notification of any price increase and the right to renew the registration at the price prior to such increase for a period of up to 10 years (i.e., the price may be locked in).
For more information about your rights and responsibilities as a domain name holder (registrant), please see our registrant rights and responsibilities page: https://www.icann.org/resources/pages/benefits-2013-09-16-en.
With reference to the Expired Registration Recovery Policy (https://www.icann.org/resources/pages/errp-2013-02-28-en), Registrars must make their renewal fees, post-expiration renewal fees (if different), and redemption/restore fees reasonably available to registered name holders and prospective registered name holders at the time of registration of a gTLD name. At a minimum, these fees must be clearly displayed on the registrar's website and a link to these fees must be included in the registrar's registration agreements.
You may also contact the registry operator for (TLD) for more information on the pricing of their domains.
You can find the registry's contact information via this link: https://www.iana.org/domains/root/db
If you feel the Registrar's fees were not properly disclosed or posted on their website, you may submit the Registrar Standards Complaint form (https://forms.icann.org/en/resources/compliance/complaints/r...) to ICANN’s Contractual Compliance Team. They will review your complaint and reply to you within 5 business days.
