Porting number service atrocious

I decided to move from Cell C back to Vodacom, however, since requested to port my number from Cell C and obtaining a new customer contract with Vodacom, the customer service experience has been atrocious. I received my new phone last week Friday, since then I have tried to sort out the porting of my number, to no avail and nobody able to give me an indication when it will be done. Yesterday, I have contacted Vodacom 6 times, whereby I was cut off twice, rerouted from pillar to post and call centre agent putting the phone down in my ear. I have a new phone and contract with Vodacom, and unable to use it. Therefore, if this problem is not sorted out within 48 hours, I would rather cancel the contract with Vodacom and rather just stay with Cell C, due to the customer service is non existing with Vodacom and lack of service in resolving the matter is atrocious.
