I have purchased a Coral Telecom EPBAX from Benzfab at Bhubaneswar

From the day 1, I have been suffering like anything, every 2-3 Weeks we need to change or repair the Motherboard.

I dont get any service from Coral Noida Office also. I have been requesting them to change the system and provide a new one, but the company wants it to be repaired every time.

I am in a big problem now, please help me and guide or suggest a way out.
