I was communicating with them using email. I just found out that you can log on this website https:// support(dot)blockchain(dot)com/ to access your Support Tickets with them. It's a lot easier than trying to dig up your emails.
First time I see a dot com domain related to blockchain.info wasn't their support operating under zendesk system?
You should know by now they are using the low fees as default and you should always use advance send to manually increase the fee, That's what I do since I'm too lazy to open Electrum

I can't understand why would they even offer any support while their service is free, are they that much good to voluntarily serve the community for free?
Do they even have any mining pool or just broadcast our half fee transactions, because when you don't have the miners to include the transactions you are sending then why would you lower the fees while you know miners only will include transactions with 240sat/b?
