Vodacom fibre Month to month contract a ****!

Month to Month contract fibre contract deal and on the 6th of October the router stop working. Contacted Vodacom about the issue and they kept on blaming @Metrofibre infrastructure for no service. With the back and forth with Vodacom, Metrofibre technicians came out to my house 3 times and confirm their line is working. I cancelled and moved on to a different ISP. Now Vodacom say I owe them for Nov and Dec after I paid for nothing in October 2023. Very much disappointed and they ruining my credit score!!
