URGENT HELP/ADVICE NEEDED!!!!! Can I extend Azure Free trail with exisitng credit balance?

Hi Team,

I have been using Azure Free trail for 30 days.I have hardly used the services, therefore there is $185 credit is remaining out of $200 on last day of subscirption.All I want is extension of ONLY DAYS not the credits.I need Synapse and Databricks services to practice more which is not free and I can not afford that.

Is this possible to request to extend days by 30 more days???

I dont want to lose my credits like this :(

Thanks
