JustDial.com — Cancelling package

I took a package yesturday from Justdial, they charged 7k rupees for that as a down payment, they told to get it activated you need to pay 3k more via ECS, which will come in another 2-3 days.
Although my package didn't get activated.
Now i changed my plan i don't want that package so I called Justdial customer care but they are telling we don't have option

so please help me

thanks
