Bharat Sanchar Nigam [BSNL] — 3g service signal not available in villages and even in towns too regarding

Address:

Palamaneru, 517408

Respected sir /madam;
I mr c. Suman babu,
Medical technonologist,
Living in palamaneru 517408 town,
Chittoor dist,
Andhrapradesh.

I am using bsnl 3g sim mobile service from past one year.

The mob no is [protected]

I am shuttling from nanjampeta 517257 village to palamaneru 517408 town depending on my profession duties.

Now the problem i says is bsnl 3g signal. When i goes to village the mobile signal drop and down to 2g service after that when i come back to town signal switched to 3g service. It was happened for some months and com i lost my data for so many days.
Miracle is now even towns there is no 3g signal services.
In palamaneru town bsnl 3g services are not awailable.
My handset supports 2g/3g only.
I called to customer care [protected] and complaints regarding the problem and asked to carry forward the data solve the signal services. They said carryforward facility not awailable and says to change the settings in mobile lot of times and even they sent settings how to change.
No use with the settings. Big comedy is when i went to kuppam and some towns the signal switched to 3g mode automatically with out any settings changed.
Fact is company stopped the 3g sevicces in some towns even they not start 3g serviceces in villages.
Customer care people not teelll the truth they made to sell the products without telling and accept the truth.
Again i lossing the data without using at all. And losing monney.
Bcz 1g speed is like tortoise that is 0kbps to 10 kbps. Totally u should do needful and do the justice.
Thanks and regards
C. Suman babu.
