No install, can I cancel?

I was scheduled to have DTV installed 12/16/22. Tech came out and said no line of sight could be found and asked if I wanted to proceed to have it installed anyway or if I wanted to decline. I declined and we went on with our day. The next day I checked my account online and it said there was an issue with finding a line of sight and a new tech was scheduled to come another day. Well that appointment is now gone off of the account. It gives me a first bill estimate and it also says no bill is due until install is complete. I’m not mad about it not getting installed as I already have tv with another company, but I’m wondering if this account will eventually close on its own or will I need to call and cancel it myself? I’ve kind of just been waiting to see what happens and if I ever get contacted but so far nothing. I don’t want to be potentially charged or anything so if I need to cancel I will, although I tried once before and sat on hold and got transferred several times over the course of 45 minutes so I gave up. They said I needed to be transferred to advanced IT to cancel. But if this is a simple cancellation I will gladly wait on hold again. Any advice here is helpful!
