I am enraged right now.
Also on the verge on unsubbing.
Give us that rollback or you lost 75 % of your clients. If there are any business analysts or financial advisers in that company, please tell them to wake up.
Why be on the verge? Unsub for a while. Send the message.
If they fix it, you can always resub.
If they keep giving us this 'lip service' and poor quality, you will have saved yourself spending your money rewarding their poor work.
