Unhappy Fiber Customer

I app**** for a fiber contract last week Thursday with Vodacom and they came to connect the fiber line today.However, the technician advised that we have a fiber line at my address. He said that Vodacom need to provide me with a ****le in the meantime. I did advice them 3 times that my neighbor has fiber with Vodacom who lives at the same address but at a different unit from mine. I contacted Vodacom during my lunch and the consultant advised that she is still investigating the issue (bear in mind that I'm on the line for 51 minutes). Finally she was back on the line, only to advice that she will contact me after work at 6 pm cause they will require proof of address. I told her that I am a customer for years and they can see that my neighbor and I share different details. I work from home and Fiber is a requirement and now I need to travel to another location which is costing me a lot and inconvenient. I need my fiber line connected immediately.
