Quit a job...long rant and advice??

I recently quit a job that I worked at for literally 2 in a half days. I know it wasn't very professional of me but I have A LOT of personal things going on and that job just wasn't the right fit..so I let them know I wouldn't be returning. Ever since then they have sent me 3 or 4 emails asking what's going on, telling me they care about whatever situation I'm in and would like to help, etc. Which I really do appreciate and I feel that's a great quality for an employer to have. Seems like they actually care. Except for the fact that I haven't answered them, which I know I probably should, but I don't feel it's completely their business when it comes to what's going on. I told them i wouldn't be returning and that's that. What is really pissing me off now is the fact that two of the employees who I don't know outside of that job, are texting my phone number (that I know I didn't give to them) asking me what's going on. Like excuse me? Am I the only one who thinks that isn't ok? Like I said, I appreciate them caring enough to ask, but who gave them my number? The business owners who would have been my bosses? I don't remember ever giving them permission to give my phone number out to anyone. Has anyone else been in a situation like this? Like I said, I know I may not have gone about this in the most professional manner but I don't plan on using them as reference clearly..the job just wasn't for me and I wasn't a good fit for it and I've got way too much going on right now..should I just ask the management and employees to politely quit contacting me? Should I just keep ignoring them? Not sure what to do...please no rude comments about how I'm handling things, etc...thank you..
