Mts — About UPC code

Address:

Erode, Tamil Nadu

Hi sir,
I am Hariprasath from Tamilnadu - Erode District, Im using MTS Network for the past 5 months. Now i wish to change my network to TATA Docomo. I have tried many times to get UPC code from MTS NETWORK and I have registered my complaints to the customer care executives nearly 20 times.. There is no response from them. They din't gave any valid reason for this delay. I was fed up. Don't know what to do now. I hope you will help me to change my network.
