Ackermans and or Tenacity inc ruining my life

Ackermans and or Tenacity Inc are ruing my life. They have just put my name on ITC for non payment fir my credit card whereas my i did pay and sent them proof of payment.

i made the pay on the 1st of feb 2018, called them the following day to confirm if they did receive the funds and i was advised to send proof of payment of which i did. from there on iv made more than 10 calls, sent more than 4 emails and sent them whatsapps but nobody cares. all they is tell me about their SLA and to send proof of payment which i have sent 4times. today the 22nd of Feb 2018 i found my name on ITC this has happened even after i was assured by one of their consultant that this will not happen as i have sent proof of payment. Iv have spent more than R300 calling them everyday to solve this with no success and their consultants also refuse me a chance to speak to their manager. i hope someone from Tenacity who cares about customers and doesn't see them as numbers will see this and do something about it.
