Horrible service provider

I called Protea metering for two weeks straight to report a faulty meterbox. I was taken from pillar to post until a technician was sent to check my meterbox after I had called for weeks speaking to different agents. Then finally about three days ago I got a new meterbox installed. I then called them to ask about the units I had in my old meter box, I was told the technician has to do that. I then called the technician who came through and he told me that the people at the office need to credit back my electricity. I then called again and was told matter is being escalated and I’d get a call back. That was two days ago. I’m so livid because when they want you to pay they know how to communicate and will send you a million sms’s and emails but when they must provide accurate service they take their precious time as though they are doing tenants a favour. They have horrible service. Now I have little units left meanwhile they are taking their time to credit my electricity from the previous meterbox back.
