Vodacom Fiber services

Vodacom have sent me my invoice for payment with this reference (Vodacom invoice and statement ***6). On the 22 Oct, I reported that my fibre service is down to which I received the following service request number SR ***

To date (5/11/2021) my service is still not restored because your "contractors" are unable to help me, and yet the other houses fibre in the street i live in are ok. The technician who was sent out eventually on the 2 Nov could not repair the fibre, hence Im still waiting 14 days later to have my fibre services restored.

Therefore why should I pay Vodacom the full monthly amount for Oct? Im only willing to pay for the 21 days that my services were on. Gatvol
