Contract cancelled before new package starts

I haven't been able to dial out all day today 31/01/18. Eventually got through to call centre and was told it is because i did an upgrade earlier in Jan and my package is only effective from 1 Feb and that there is nothing they can do. Have been a contract customer for 20 uninterrupted year. I was told that it's because the package has changed. It's not my fault they keep changing their packages. Why can't they charge me a pro-rated amount until the new contract kicks in. I cannot work. I have a 140 km trip home today and if i have an emergency, cannot dial out. Since when is it ok to give your contract customers interrupted service? On top of this, when i did the upgrade, the person I spoke to could barely explain the benefits properly. When I phoned back to check, i was told that they couldn't see on the system what special arrangements the consultant had made. On top of it , I was told I have to phone back in Feb or March to get the extra data they promised me because the consultant can't load it until then! I was actually going to cancel my vodacom contract and go to Telkom and the consultant talked me out of it. After this latest incident of having my outgoing calls cut for the day I definitely wont be remaining a Vodacom customer! And, I want a voice recording of the original call I made in January when I did the upgrade.
