Upgrade due - Business call centre always on hold

MyVodacom (online) reports one of my numbers ***) is due for upgrade on 13 August (today). When I look for deals it then says that this number is NOT eligible for upgrade?!<br> So over to call centre: Being a business client the regular upgrade department cannot help me so I have been forced to contact *** (Something I was desperately avoiding after having had an atrocious experience last time I did an upgrade). At least they answer the *!@#$ phone, though.<br> Once again I am APPALLED that the business call centre is so poorly/inadequately staffed. I am ALWAYS kept on hold for AGES, then cut off with a \the number you have dialled is not available"message to rub salt into the wound.<br> PLEASE PLEASE"
