City power and their failure to deliver

We paid for a prepaid meter to be installed last year to date no one has come and they falsely logged on their system that someone did come last year. I been contacting them spoke to Brian and Mpho in the contact centre they say the people will come yesterday no one pitched my husband took a day off to wait for them. Phoned the contact centre again yesterday Mpho advised I should wait till 12 midnight for the electricians. No one came. This is pathetic we pay for services have to take leave to sit and wait for someone to show no one does. No one has any answers. As it is we pay a monthly bill for people to come read the meters no one comes then 3 months later we get a huge bill that we cant afford then have to make payment arrangements. Please can someone let me know what is happening.
