Vumatel ****** money from innocent clients

I was extremely happy when at last fibre was available in my street and order my Line from Fibrehoods in January 2017. the package I chose was from Vox Telecom with a FREE INSTALLATION as per the details on the Fibrehoods website. All went well and I been enjoying the service for the last year and 11 months. In October i received an SMS from Vumatel stating they account show I own them R1725 installation fee. I contact them and advised them about the fact that I took the contract through Fiberhoods and Vox Telecom which included free installation and they need to talk to them. also how can they contact me almost 2 years later with demand for payment even though i never signed an order with them or had any dealing with them (all dealings were done through Fiberhoods and Vox) Vumatel assured me that they will contact the service provider and will "sort it out" Today I received another SMS stating that they had a "meeting" with the service provider who refused to pay and i owe the R1725 installation fee. I call the call centre of Vumatel again and Spoke to Fatima Puckus who could not send me any proof or any document that I signed as there are any to show I own these funds. then when she saw she cant deal with it she promised to get her manager Leona Hewalt to contact me. this is ridicules, Vumatel waited for 23 months after installation and with no documents supporting their claim alleged that I own them for the installation order they received from Fiberhoods. If i signed an order with you please provide the paperwork showing it. so either your admin department is in a mess and have no clue whats going on or this is a deliberate attempt to ****** money from the innocent public under false pretense. I eagerly await to Vumatel to come back to me to resolve this issue.
