No response from Vodacom

I've been informed that the investigation found in my favor and that the modem needs to be collected in order for the contract to be terminated. Since September 8th, I have been waiting to hear from someone. I contacted the cancellation department on the 13th to find out when the courier to pick up the gadget would arrive, but they were unable to provide me a date. Vodacom is failing to inform me of the time that the gadget will be picked up, and nobody is speaking as I am running out of time to guess.

I'm eagerly anticipating Vodacom reply.
