Must be the worst customer service ever

In October 2019 I posted a review of the poor and disgusting customer service I received not just from agents but management as well and there were two separate calls/ cases logged to get "CellC" to rectify the mistake that was made on there side and to come back to me with there way forward of making sure it does not happen "apologie" with the billing and the fact that their mistake lead to my line a business line been cut for two days's I lost money "but they don't do apologies or know how to call back I wonder if they even took the time to listen to all the calls but I'm not important as a client", a month later and I finally get a call from there billing department, and ques what, my billing is wrong again after the last mess up I just don't get what they do. take it next step my line is getting cut
