Bad service Mweb

I have been with Mweb since I had my ADSL line and never ever had issues with them. I moved over to Fibre and still, everything is good no issues. About a month or more ago, I could no longer access my work websites and was up and down between Mweb and the IT guy at work. IT said it was my ISP my ISP (Mweb) said it is my works network that may have blacklisted my IP address. No one called me I had to make all the interactions. There was one technical person Eugene Goerge who tried to assist. As it all turned out the error is with Mweb, I got so tired and cancelled and will be moving to a new ISP on 26 Aug. But I paid for the month, I work weekends, I have no connection and have been sitting and working at family members homes. Is it because I now cancelled that I am not even bothered with? The reference number for my case is MWB***5
