ESIC — not giving treatment

my IP no.[protected]. i went to the esi gandhinagar branch for my mother's eye check up on 9th March of 2015. they gave reference slip to ESIC GORIMEDU main branch. Esic camp was conducted on 10th March. i went to the camp, vasan eye care staffs were checked my mother's eye and they told that operate your mothers eye as soon as possible, but they haven't tie up with pondicherry Esi for that they refer to the Cuddalore branch. . i went to the cuddalore vasan eye care& they told that pondicherry esic card is not valid for tamilnadu esic.. Again i came back to the gorimedu esic hospital and undergone consultation with the doctor, & the doctor told that we will refer only pondicherry GH for this purpose& not for any private hospitals. Sir now i want to know onething from you, what is the use ESI. then why we are paying money for ESI. i already send the compliant to puducherry ESI office they had not given any reply.
