Empty promises and poor customers service

Got a new data sim contract from Vodacom. Now that sim is activated I cant transfer data to my other vodacom numbers,because the vodacom app is not supporting 067 numbers yet. Also the options on *135# also not allowing to do so. That was not the agreement when I took out the contract with Vodacom. Also the after sales department cant help me due to their systems being down and they dont know when it will be back on line. So I cant even cancel the contract which I was informed by Vodacom when taking out the new contract that I have 7 days to cancel after sim activation. Vodacom is quick to sell products to customers but to assist them when there is problems they failed me.
