No Delivery and no communication of delivery date

I contacted Vodacom on *** to cancel my contract and move to Telkom mobile.They convinced me to stay on offering me a better contract&that my phone would be delivered to me last week Thur/Fri. Since then I have received 3 smses saying my phone is ready for dispatch.Today I called Vodacom's upgrade desk to find out when I can expect delivery since it is after the quoted date,after waiting 30 minutes I go through to a consultant who says my phone is in backorder which means it is not ready for dispatch.I get put through to another number *** who claims phone is ready for dispatch. And I must call the upgrades line again to find out when it will leave the warehouse.I then speak to someone else who says it will be dispatched tomorrow or Mon, when I ask her why I have not received the data/minutes for the new contract yet she puts the phone down on me.I call again, wait for another hour for the phone to be answered.Finally an agent answers.He says my phone won't be dispatched as they have not invoiced&and can't tell me when that will be.The new contract data/minutes etc will only be effective from 1 April and I did not receive my old contract mins etc. Can I get some service?
