My Accounts are a mess

I have 4 contracts with Vodacom.<br> <br> For about the 4th or 5th time I am unable to buy a data bundle online on my main data contract *** because their system says I am not the master account holder. I AM!! I have phoned in about 4 or 5 times for this same issue, they correct their systems, but the same **** keeps happening. 15 mins a phone call!! <br> <br> Also on my 2nd voice number, ***. insurance of R245 has been added to this latest invoice without me signing for or requesting it. How is this possible?? <br> <br> Can someone senior who knows what they are saying and doing please fix my account. It is beyond annoying now. The service just gets worse and worse.<br> <br> Thank you
