About

GSM Services is a well-established company with a large customer base, but recent reviews show a significant decline in satisfaction. While many long-term customers still praise the professionalism and knowledge of the technicians, a growing number of reviewers report poor communication, long wait times for service, and aggressive sales tactics. There are frequent complaints about the company's inability to handle emergency calls for loyal customers and issues with the consistency of service. It appears that while the company has the capacity to do great work, their current operational challenges are negatively impacting the customer experience.

User Feedback

I've been a loyal customer for years, but the service has gone downhill.

The technician was great, but the office is impossible to deal with.

They tried to sell me a new system instead of fixing the problem.
