Vodacom cheating loyal customers

I cannot believe how I struggle to upgrade my contract. I used to have R299 (Were the overchange met with R42 everymonth) So I paid R341 every month. I wanted to upgrade to the R499 100MBPS with router but it does not allow me. An Vodacom agent phoned me on the 23rd of November and he also could not get it work On the 24th of November still nothing. So I struggled. I tried on the 24th a different contract and then it went through On the 25th they phone me to confirm everything, Then I said I want exactly the other contract, so the agent says she cannot assist she will get some to phone me. NO ONE PHONED ME. On the 29th of November I phoned and the person says no I cannot get a new contract because of the upgrade. If I know that then I should not upgrade at all.

I am still waiting for the phone almost after 2 weeks. Not happy the overcharge me with R41 per month

Luckily Telkom gave upcapped, but I would prefer Vodacom as I always had good server since 2003 but I think it is time to move away
