Problems with Vox Telecommunication

I am a new customer of Vox Telecommunication for wifi and I am extremely unhappy with the way that I've been treated so far by them.

I have requested that my service with Vox must only be activated on a certain date after installation because I was still at the time with another Wifi provider and had to give them a month notice which I did. I told the service agent in our phone call and WhatsApp messages when to activated(date) my account with Vox and he confirmed it twice to me(Voicenote recordings) but Vox ignored my request later and straightaway activated my account without my permission and knowledge. The Vox decoder was plugged out and not in use after all installation was done. I did so because my other service was still active and that wifi decoder was in use and was plugged in for the notice period. I have now been billed by Vox for the monthly subscription and also Pro-rate for the time period they activated my service without my permission for a service I didn't even use. I have emailed Vox(accounts Department) numerous times received automated responses back with Reference numbers but got no feedback or help to date. I paid my monthly subscription to Vox after my notice expired with the previous wifi provider ended, but I did not pay the pro-rate as a matter of Principle because of the original agreement I had with them. I feel a contract has to be honored as agreed upon more so in business. I received another email from Vox on Monday informing me that my account, service will be suspended in 7 days if I don't pay the Pro-rate. Vox doesn't answer my emails back and the Account Department said they can't help me and don't know of any such arrangements when I phoned them. I don't believe this is the correct way to treat a customer or to handle a complaint..
