Poor service

My data sim has been out of service for the past 8 days. I called Vodacom customer care concerning the matter and was told to do a sim swap which would cost me R65. I did so and the new sim still indicates “No Service” . This reflects poorly on Vodacom’s service as the contract has already been paid however, I can’t even use it !!! I’m highly disappointed with Vodacom and want to cancel my contract with immediate effect!
