Upgrade declined after having an account for 10 years+ !!!!!

I have been your customer for over 10 years now & you took my money via debit order. I am under debt review for almost ten years & I still paid my account in full EVERY month. I have done upgrades every two years for 10 years & I am due for an upgrade now, but my upgrade is being declined due to the fact that I am under debt review. I own four Vodacom contracts, but it will eventually become 0 now that I can't upgrade anymore. Isn't my money good enough anymore? Doesn't my payment history for 10 years mean anything? You suc****!!
