Vodacom is the Pits

Vodacom is really the pits, I bought a home router on contract in Oct 2022. The router worked until 24 Dec 2022 when it wouldn't go on. I booked in at the Eastgate Service and collected it on the 24 Jan 2023. It worked perfectly until the 18 May 2023, I took it to Southgate and collected it today (17 June 2023), and guess what? It is still not working.

How is this fair when I pay for a service that I don't receive, for a fault that is not mine? It's a full month that I don't have wifi and yet my account gets debited without fail.
