Netplus Broadband - Cheated fibre plan

I'm Ab Rashid lone from baramulla, I'm using netplus fibre service, the worst fiber service in this world,
I did fiber recharge ****rs for * months.
Speed was **Mbps, after used few days i got notification about **% data consumed, i just ignore it, it may be a wrong message, but after few days my speed goes low only **Mbps, i checked app it was showing **GB consumed, available *GB.
I goes confused, what is this, i called my friends , other netplus users, they told me it's not possible, nobody helps me, then after ** days i wait,
I wait for may be my another ***gb will come in this month,
But nothing happen, i did too many calls to customer care, nobody helps me.
At last they told me do mail for plan migration, i did two times, they open ticket and close, but nothing happen,
Now they were saying buy new plan,
It means my ****rs loss.
How they can easily say this, buy new plan. Please help me...
