UNFAIR SUSPENSION

I'm facing a situation where my accounts I suspended, I can't run my business because of their stupid employee who assured that there won't be any interruptions to my accounts after trying to make payment arrangements with her for my contracts. The stupid telkom team decided to handle my accounts to external collectors wherelse I did try to make payment arrangements and they promised no interruptions, they'll double debit this month. I've been their loyal paying customer for more that 4yrs now, for missing ONE payment of which I tried to make payment arrangements of, decided to suspend my accounts hand over my accounts to external collectors.
