Disappointed vodacom

Good day I have been a customer at vodacom for the past 14 years. I have 2 phone contracts with them. Which i pay monthly a amount of R579.00. Now i am due for an upgrade. I went to vodacom in rustenburg waterfall mall to upgrade the lady took my numbers and check and confirmed that i can upgrade. Great i choose phones just to be disappointed that i cant upgrade something with a portfolio. I went home and phone customer care 111. After been on the line for almost 40 minutes and been transferred to one consultant to another no one could have helped me. So i went back to another vodacom where they assisted me telling me that my account have been reviewed and my finances have been taken away because i am on debt rescue. 1st of all i have been there for years now and in 2018 i did upgrade with no problems 2 years later i have to pay cash for a device and still pay monthly my contract fees. No one notified me that my account had been reviewed and they took away my finance. 2ndly my contract is not part of my debt rescue. I feel this is unfair to me who have been a loyal customer with vodacom for the past 14years now. Can you please assist in this matter
