Do not upgrade with Vodacom

I called Vodacom cancellations to cancel my contract and move to Pay As You Go since I wanted to port my number and move to another service provider . The agent then offered me a contract similar to the other service provider so I decided to upgrade and I was told I will receive my device latest Monday 12 . It is now Tuesday 13th , no call from Vodacom . Called Amanda *** was said the device will only be available Thursday so I can expect delivery next week...I cannot wait that long , please cancel this contract immediately , I will move to another service provider
