No Help or Stock 6 weeks

I have now been to both the Telkom store in centurion mall and the store in mall@reds trying to 1stly get a LTE-A contract and an upgrade on my completely unlimited contract with no luck after 6 weeks still no stock and no one is prepared to even do my application in the interim I can't call the store as they openly admitted they don't answer the phones or just leave them of the hook so I have to go to the store every Tuesday and Thursday in the hope they have stock. I even tried calling the call centre and no luck as no one answers the call after holding on for more than 30min at a time. Some help would be great.
