Realtor wont return call or texts went Dark

[Jermell Shavers]

I’m an OOS investor and the realtor was good on the first go and this time around she won’t return calls or text it’s like she just went dark. What could be the reason for this ? I paid cash last time and I’m paying cash this time. Why do realtors do this ? I wanted to ask before I leave a bad review about her.
