I used 2 TATA DOCOMO Sim cards in a CUG plan for three months. After 3 months I send a request for MNP to TATA DOCOMO, Because the signal strength was very poor in major cities also, And very bad customer service too.
That time I went to nearest TATA DOCOMO showroom to pay my last month bill, they told me to that you have to pay extra 7 days usage charges for advance payment mode. I just agree with that deal. After 7 days The MNP Process was done. My new service was opened in VODAFONE NETWORK. After some days I received A call from TATA DOCOMO CUSTOMER CARE EXECUTIVES.
They told me to that you not paid Our extra charges. Really I was shocked, just I told to executives I was clear my all bills and accounts. Then the officers asked sorry for disturbing me. 2 Days later they repeated the calling process to my number That numbers 9042070207 and 9042070206. After 1 day the connections are disconnected. Really TATA DOCOMO IS A VERY BAD NETWORK. And showroom staffs are Misbehaving with customers. I need my Sim cards with proper connection. Aswin.R.Raveendran 9092979091
