Bad Service when upgrading

The whole process for upgrading a contract on Vodacom was a nightmare. Firstly, the online store does not work. I placed 2 upgrade orders on the online store. When called Upgrades dept the next day, they had no orders for my upgrades, even though I had reference numbers. Another issue is that my numbers are on an old system, which only certain call centre agents have access too. So I always get transferred, and keep getting disconnected. Now I cannot do a sim swop, because according to Vodacom, I have exceeded my limit to calls to customer care....does'nt make sense. I can't even call to complain, because I can't get hold of anyone. I am really frustrated.
