I am writing this review to share my customer support experience with SPACE SERP, hoping it will be helpful for other users and encourage the service provider itself to improve.

My issue began around late May 2025, when I became unable to use core features of my account, specifically the API Playground and API access. What's particularly frustrating is that while I can log into my account and my credit balance clearly shows sufficient funds, the system continuously displays the error message: "Not sufficient funds for this action." This is an illogical and extremely annoying error, as I have thoroughly checked and confirmed my credits are fully available.

This marks the third time I have contacted support regarding this issue. My first email was sent on May 27, 2025. I have waited patiently, but the delays in responding and resolving the problem have become unacceptable. The fact that my account is not functioning correctly, especially this erroneous credit-related issue, is severely impacting my daily work.

As a user who relies on SPACE SERP for critical data analysis, SEO content generation, and keyword research for my projects, the failure of core features and the lack of timely resolution have led to:

Missed critical project deadlines.
Inability to deliver products or reports to clients on time.
Significant decrease in productivity, causing considerable loss in time and potentially financial implications.
I understand that technical issues can occur, but what frustrates me most is the inefficiency of the support process. After multiple contacts, I have yet to receive a concrete solution or a clear timeline for when my issue will be resolved. Feeling neglected and not receiving the attention I deserve from the support department is truly upsetting.

I sincerely hope that SPACE SERP will take my case seriously and take urgent action to fix the "Not sufficient funds" error and ensure my API functionalities are fully restored. Furthermore, I expect a significant improvement in the customer response and support process to prevent similar negative experiences in the future.
