Dispute Staus

I thought I initially submitted a dispute back at the beginning of March and never received anything so decided to fill a new one and this time received a case number. I’m fine waiting patiently but do want to assure my dispute was revived properly. 

It’s not a dispute concerning charges and I have also switched carriers. How does one ensure they are waiting on a response if they are not sure it is fully revived and can check the status? 

Thanks,
