Bad service

I refer to ***. i keep receiving emails from Brooks that i owe money, when i call their call centre thy say i was handed over by standard bank. i called standard bank and they were not aware of that and asked me to request for statement from Brooks and they failed to do so till today and this has been going on for over 3months now. The only money i owed standard bank was settled with MDB and i have sent all those documents (Paid up letter) to Brooks incase its a same account but still they have failed to remove me from their system (as this is affecting my credit profile) i have also been sending emails to Teboho Masimong, *** but still not receiving any joy. may you kindly prioritize this case as it is having a negative impact on my profile, i need to purchase a car and this is affecting me
