Incompetence poor Service

I Paid our electricity bill on Thursday 26 July 2018.I received a final demand the day after I paid and ignored it because I knew I paid the previous morning & today I tried buying electricity online and I'm blocked! I call their After hours center & the Guy can't go into mbombela offices to help us because the business Complex Closes it's Gate at 6? Why do they even have an after hours Helpline if they can't do anything to help us? Why does Mbombela Lease from a Building that Locks Gates at 6pm? I'm so annoyed with their services. Why am I blocked after I have Paid my Bill? My entire family must bath with cold water tonight and tomorrow morning because of Mbombela employees Incompetence! I'm so disappointed with their **** service. Jerr!!!!!
