Telkom Contract Circus with no way of helping the client, take it or leave it

not happy with telkom, did upgrade, wrong device delivered, send device back, device was cancelled and number to be upgraded was put on pay as you go without notifying me or ask me what would i like to do, no response from telkom regarding this issue, last week i was able to qualify for new device (upgrade)and this week i am not qualifying anymore????also no option to take out new contract???? how in the world is this possible , not even 7 days after initial application (where i was able to upgrade) now im not able, thinking of cancelling all my existing telkom contracts , number to be upgraded on prepaid but when trying to load air time or data it does not give me the option, (the requested number is not available at the moment try again later, restarted the phone and still nothing )
