Business ProfileforCCUSA

In January 2020, I applied to CCUSA to spend the summer on the camp ******* program, I paid an application fee of 40 and an acceptance fee of 190, in March I paid the final deposit of 145 - total 375, however when the covid pandemic hit, the camp made the decision in May 2020 to cancel. 20.05.2020 in an email under "rollover policy update", I was asked if I wanted a refund or to roll my fees over to the following year (2021). At no point was it communicated that after this point, the program terms would be updated and refunds would no longer be made available. I decided to rollover my fees to the next year, however on the 25.08.2020 (3 months later after being asked to commit to a decision), I was asked to sign the 2021 program agreement, I never did sign this or progress my application, I was chased multiple times but I was wary about travelling to America and was wanting to explore my options of transferring my application to ****** so held off as you can see in the emails, the same thing happened again and on 21.06.21, the camp again decided to cancel. As these decisions were affected by covid and ultimately made by the camp, I contacted CCUSA to issue a refund to me but have been totally refused any form of refund telling me that the updated program agreement stated this and that only rollover options were available, however they asked me to sign this updated form after first asking me to commit to a decision without communicating these updates until 3 months after the decision was made and the form was never signed. I do not feel it is fair or right that CCUSA should hold my money when they did not provide any service or goods and did not fulfil what I signed up to receive, particularly when the decisions were out of my control, no updated terms were signed and these were updated in a unfair and deceiving way. I appreciate any advice on my rights and in gaining a refund for the payments that were made. 

Many thanks in advance,
