Vodacom Customer Service-what service?

I have tried on numerous occassions to get through to your customer care line-with absolutely no success!

In about March I increased my data package and also took out a router The router was for my daughter who was at Stellenbosch University where the WIFI in her residence was not sufficient. The additional data was for me for on my mobile for work purposes. With COVID-19 my daughter is back home as am I. Our home has fibre and thus none of the above is being utillised.

My questions is this-are we able to put a "pause" on the router package and on the additional data for 4 months and Vodacom add this period to the end of my contract? That way I am not paying for something I am not using but will use when we are back at work and at Varisty?
