Worse experience

Mtn Parow I cancelled my mtn router and sim card with them on the 4th of April 2026, left the router with them, I was told that a cancellation fee of R670 will be debited end of that month, 2 months later i am still paying for the router, while they had it, been phoning the call centre for 2 months with no luck, I eventually went back last week saturday, i was told that the sales consultant shouldve let me paid the amount in store, had to refill in the application, paid the cancellation fee, then i got an sms saying that I have an outstanding amount of R700, which i will not pay, they should be giving me a refund for the 2 months that they debited while they had the router. Been trying to call them with no luck, worse customer experience I’ve received from their call centre as well. I want my refund and this contract cancelled!!
