Telkoms empty promises Fixed wireless contract

I have an account with telkom, acc number: ********** 36038. I have/had a wireless landline with the contract, which I had to buy. A couple of months after I was given the phone the battery stopped charging - there was now something wrong with my phone. I took it back to Eastgate where they confirmed that there was a problem with the phone and I they told me they did not have stock and I can get a phone at Festival mall - this branch had phones however all were for their clients. Long story short - I took the phone back to the Eastgate branch with them promising that they will call me as soon as they have stock. I have now been waiting for a couple of months without a new phone and now Telkom is busy rolling out the same phone for free to its other customers. How does this work - we are informed to wait for Stock and meanwhile the same stock we are told is not available is being rolled out to people who are not paying for the devices. I have waited for too long.
