[Resolved]  Hathway — Harassment by calling multiple times a day

Hathway calls me more than 10 times a day even though I asked them not to do so. I've tried calling their customer service many times to ask them and activate the do not disturb service(if they have) but there is literally no way to reach them. The last conversation I had with them on call was that they were asking me to do the recharge, he said:" Sir I'm staying on the line, recharge now so that there won't be any further disturbance from us". This is literally a kind of blackmail so I'll have to have the recharge to be at peace with them or else they will keep calling. I want to sue this company for all the harassment it did to me.
