VODACOM POOR SERVICE DELIVERY YET AGAIN

Once again shady tactics at work not surprising and not my first poor delivery and bad service from this provider. Paid for a 30GB PLUS 30GB ANYTIME and 30GB PLUS 30GB NIGHTIME --- YET recently I'm only Receiving 30GB PLUS 11.35GB Nightime. What ******* is this. I did not change my contract. ITS Valid for 24months my Monthly supp**** data should not change as fixed in my contract you ****. If this is not rectified I will be cancelling both my contracts this year !!! Have had an issue every contract I HAD with you experience the same poor service delivery on contract issued to a customer. You still remain like the rest of this country shady, poor service delivery.
