Leaving chats before we concluded conversations

Recently changed my address moved to a gated community and I was chatting with a consultant via the app 1st they join the chat then leave the chat, I'm not sure wat kind of service is that, had to go through 3 people doing the same thing, did not get the other people's names but the 1st name was Boipelo, the 1 I remember was keneiloe papo...they just join and left the chat.....so I ended up talking to dimpho dikobe who assisted but not fully coz she left the chat as soon as I had questions and we were not done with the conversation. So is if i am getting such ****py service just to change my address what more when I wanna claim am I gonna go through this where ppl leave as they please and they not bothered if we done with the convo or wat?????? I am not sure if my things are changed coz there was no conclusion, plz assist
