Access restrictions to internet sites

Access is blocked to most internet sites with a pop us that I am under 18. I visited the Centurion Vodacom 4U shop twice in an attempt to resolve this. Both times I was told to contact their *** number as they are unable to assist with this query. Both times I called the *** number, they referred back to the store. On my second visit to the Centurion store, I asked for the manager, he said he would log a call with head office, blah blah blah. <br> <br> I will not return to a Vodacom 4U store and if this is not restriction is not removed in the next week, I will instruct my bank not to honor their debit order
