Issues with data bundle again!!

Have a data bundle on contract. Once again I am getting a message that the data bundle has expired and that I have 0 MBS available on this 1st of the month. The Number on my SIM differs to the number on my account. What am I paying you guys for?? <br> <br> This is absolutely of no use to me if this keeps happening. First I get a new line vetted against my name WITHOUT my input and when I inquire I am expected to give you information for security purposes. Yet where were those SECURITY CHECKS when the line was vetted without my input???<br> <br> Sort this out today or cancel the contract due to non delivery from Vodacom in this regard.<br> <br> Furthermore. The constant non delivery or receipt of SMS messages to both my lines has become a problem. Free SMS with my contract counts for NOTHING if they cant be delivered or received. The level of the service from Vodacom has declined so much that there is no longer a reason to support the supposedly BEST NETWORK in SA<br>
