After i submitted the information, they said they would contact me through email.
After few days without a email, i contact them back through live chat, asking when will i get a response, a agent comes and tells me the original decision remains because i "didnt respond in the given timeframe", when i did respond in all timeframes and they rejected my case because i "didnt provide asked documents".
What do you think of this?

Provide all evidence of your replies that took place within the given time frame.

Then ask them to explain why they've stated otherwise.
