Vodacom One Number issue

My One Number all of a sudden stopped working a month ago. After endlessconversatuons with vodacom I was told to go into the store in Cresta. After going in store I was told by a technician that the Vodacom One Number service no longer works and there is nothing they can do. How is this acceptable when it is a service I am paying for and how come none of the Vodacom staff members I spoke to were aware of this issue? Either the technician is lying or vodacom has not made their staff aware that this is a nationwide problem or it's just easier for them to say "sorry there's nothing we can do, it's not our fault" because they're either too lazy or too *********** to try and find a solution. Disgusting service as usual!!
