Absolute useless service

I have 2 telkom business mobile contracts that is due for an upgrade, I have tried upgrading through telkom shop Klerksdorp for the past 6 weeks who is unable to locate the devices that I want to upgrade to. I have tried online, and when I enter all my details the online store keeps loading, I have tried phoning in, but everytime I phone *** I go through to the contact centre that tells me to call 10213, when I phone them they tell me to call ***. Can any one from Telkom please get back to me regarding how to upgrade these accounts.
