Can I still get in to UCF?

Hello,
So, I got accepted to UCF in May.
I wasn’t sure if I wanted to go or not,so I accepted their offer but didn’t pay the admission deposit. I decided not to go after that and sent an email to the orientation lady. She said she deleted my account. Now,after a while, I figured out that I wasted a big chance and want to go back to UCF. Do you think they can let me go back?? I got accepted for summer by the way and my MyUCf account wasn’t working properly because of some technical difficulties: it says that my residency term is bigger than my admit term and it asks me to call a number. I tried to call them alot,but no body responded at all. Can I,for example, use this issue to excuse myself for not paying the deposit??? By the way, I haven’t dropped out completely yet.
What can I do to be able to go back???
Please help me as soon as possible cuz time is not on my side.
Thanks!!
