Worst service would be an understatement because there was none

Last month I placed an order for the Fibre Network since my tenants have been complaining about signal issue. I was told to make a payment which I did and sent proof of payment. They then sent their rude technician whom I had a personal encounter before so the person just stood by the door and spoke to my children that the office will send a technician and then left. Since that day I have had nothing from them, it's now over a month. If these people don't want to give me service, the must just give me my money back. It is clear that this guy calls the shots at Vuma that I will not receive service because he's immature and unprofessional. I blame the ISP as well because I have raised this concern and they decided to ignore me and keep my money.
