Avis Tzaneen's service is shocking

I rented a car from avis and dropped it off at the Tzaneen branch in June 2019. One week later I asked for my invoice at Avis Tzaneens office. They could not assist me. I literally went to their office three times and every time they say their system is down. It's been down since 9 June till 19 June 2019. They don't have phone lines or internet.

The assistant there took my details and promised to send my invoice. Three days later I called to ask again and she says it's not her fault as she can't get through to anyone to help her.

I needed to hire a car again and asked them if they can assist me. I was told they can't but I must go online. My wife then asked them if you can't book a car with them or get your invoices from them what work do they actually do. We were told they receive the cars and hand them out again only.

I'm totally shocked to get service like this from a national company. It has left a really bad taste in my mouth and I don't feel I want to use them again but unfortunately tzaneen only has one rental company.
