Reliance Communications — special call rate offer of 8 rupees got deactivated in just 8 days

On 10th september, i registered a complaint here. Been days since i registered a complaint here regarding my call pack. Yet there is no resolution to it.
Do i have to wait till ages?
Really fed up with reliance telecom.

My reliance prepaid no. Is [protected]. I got an offer of 20 paise all calls per minute for 90 days on rs 8/- recharge. I got my no. Recharged with this offer on 31 august"2017.
These messages were sent from reliance...

1) recharge rs8 successful. All local n std mobile n landline calls at 20p min credited into your account for 8 days.
2) congratulations, now you can make all calls at 20p min at any network for 90 days on successful recharge of rs.8 rcom.
3) congratulation! 8stv has been successfully activated on your phone. Thank you. Reliance

This offer worked successfully for the first 8 days, but after that period, the calls are charged at 1rupee and 20 paise/minute.
This was a special offer on my number, and despite receiving the confirmation message from reliance for activating this offer for 90 days at low tariff, how can i be charged higher for my calls???
It's absolutely nonsense. Every 15 days, there's one or another issue arising, say it be slow network and long hours for daily renewal of internet data, and now false promised offers.
Need a resolution over it.
Don't have ample time to keep writing to you guys.
Improve your services.
Soon extend the promised 90 days validity for all calls at 20 paisa/min on my no.
Truly a disappointment.
Several times i had put a complaint here, but all futile.
Till now, no resolution been provided for my complaint of 8/- rupees call rate pack.
Today too, when i made a call, i was charged 1rupee 20 paise/ min.
Reliance is a fraudulent company. Firstly they give special offers, and when u get it recharged, they discontinue the offers after a while.
Shame on you... What a cheap way to make fast money.
I need a quick positive response.
Can't loose my hard earned money on higher call charges, irrespective of getting the call pack recharged.
