CANT migrate to bigger package within 3 months.

I Upgraded my data package 3 weeks ago to a 50G pakage (+30G at night)for R329. Now during lock down I see that with the kids homework and more data, we will not last. I asked to get a BIGGER PACKAGE. And they said it can only be done after 3 months! I am not looking at going smaller, but bigger. More business for them and they are flat out refusing to do this and not at all with a logic reason as well. NO REASON and absolutely no thought of service: "lets see what we can do Sir..." LUDICROUS! I got a quote to Migrate to 100 G and it was R 1258 for 24 MONTHS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
