Upgrade retention department

Vodacom retention department. September I did phone upgradevia call center, when talking to the consultant I asked him specific question on porting my number from mtn to Vodacom existing contract, his reply was yes it wouldn't be a problem to port the number as soon as the new package is active. One the 1st of November when the sim was active I did my part ready to port the mtn I call Vodacom to finalise the process the I get told that it's not possible. On the 1st I log a call get told that my query will be escalated and resolved by Monday. On Friday team leader calls to reassures me that by Monday the query will be resolved. Monday no calls nothing until Thursday where I call back to find out what's causing the delay. Only to be told nothing can be traced regarding the query they have to start the investigation again this will take another 48 hours. I'm not interested in solving this anymore.. Vodacom must send someone to come pick thier device and cancel the contract.
