Netflix complaint: Not helping not responding and left chat in the middle

i was talking to an agent about charging twice from my account for a few months as I checked that recently I talked to one agent about my $14.99 monthly subscription but I got charged $21.46 and $18.99 again in the same month.
The agent told that he can only refund that 21dollars the rest of double charges I have talk with my bank about it. I talked to bank and they clearly mentioned that Netflix is the one that charging you Bank can’t do any thing in this you have to talk to Netflix customer care again . So I again reached to one agent, while I am explains the situation he texted whatever he said and disconnect me and connect me to another agent or manager.

I explained again everything and even said sorry for this long and trouble situation, they didn’t even respond to me also they texted like we can go back to only 3 months and only that 2 times $18.99 will get refund and they stop. I tried to say thankyou for helping they are not in chat.
I asked if any one there in chat still but no response,
I am trying to give them details about that double charges but no one there for me as I am keep texting and asking details about that like I was left in the middle.
