YUMIYU review for Omnisend Email Marketing & SMS

It's a scam! They kept charging me $800 every month. I had around $1600 SMS credit in my account, I wanted to downgrade my email plan and they took ALL of my credit away!! There is NOWHERE says if you downgraded email plan, your credit will be gone! I paid for $1500 credit! Give my money back!! After talking to their support, Diego, I told him I will upgrade my plan back and just give my $1500 credit back to my account. He said he can not do that, he can only give me $599 credit back??!! In less than 24 HOURS AGO, there were at least $1500 SMS credit in my account, even I told them I will undo the cancellation, they still want to steal my money! This is extremely unfair to the user and it is very unprofessional. Diego is trying to steal my credit. First, there is no alert or info says that I will lost ALL my credit when I click downgrade my plan. Second, even if you undo to downgrade in less than 24 HOURS, they will still take YOUR MONEY! I have been using omnisend for almost a year now, this is extremely unfair and disappointed! I will never recommend this app unless you will use them forever! or they will definitely take your MONEY!!
