Address:

524001

Sir
Namaste
I am p m gopalachary p h f, from nellore, andhra pradesh. i am a retired head of the dept. of oriental languages from v r college, nellore.
And ex - rotarian i am one of the users of your company’s data card for approximately four years.
I crossed 70 and running 71st year. i suffer from high sugar level, b p and stent is placed for my heart trouble.
In the month of april i received email and as well phone calls
From customer care service, for up gradation from 3 g to 4g. but as my vision is not co-operating to use computer as before, so i requested them not only for up gradation and also not to provide your service from that day.
Same promotional request i was getting from the customer care service, even though, i rejected the offer. i stopped using the data card since 5th may, 2016.
But unfortunately i received bill for june amounting rs.1904/-.
Previously every month i was paying only rs.572/- whether i use it or not.
From customer care, i received a call for 4 g up-gradation. i told all the things. they asked me to visit reliance office in nellore.
There he arranged to converse with the personnel in bombay office. he talked to me in telugu language. i requested him to discontinue providing service. first, he hesitated. at last he obliged, and asked me to pay an amount of rs.2100/- though it is more than the bill amount, for discontinuing my usage.
I paid the same and handed over the data card with sim card and got the receipt for that.
Again this month i received e-bill for payment.
Today i. e., 23 of july i got a hard copy bill for rs.111 and the due date is immediate.
I do not understand what is happening for my mail and phone call request.
Please help in this regard, and relieve me from this tension.

I thank you for your patience in going through this letter.
Regards
Yours
P m gopalachary
