Dear sir/madam,
I am using the jio connection at least 2 year. I have a complain for jio network. My jio sim is fully recharged with a valid plan but my Internet connection speed is very slow and this problem is facing many jio users in my area.I already inform this issue on jio customer care but there is a no solution for me.They tell me plaease wait for few days and they tell me they have limited network at this area and they solve this issue in future. It's been 8 months already they did not resolve this issue.
Please help me. I hope my problem will fix very soon.
Thanks
