Collections Hold

So last week like on Tuesday or Wednesday, my Wi-Fi services were disconnected apparently from a house debt and collections hold on my account because of previous issues that a family member of mine had with Xfinity and her old equipment, so on Saturday I returned the old equipment and got the receipts from it, keep in mind that I payed 51.98 on Tuesday for my services just for it to be disconnected shortly afterward. I tried calling customer service multiple times and I’m always getting put on hold so I’m just trying to understand how I can possibly reconnect my services because this is really annoying [Edited: "Language"] me.
