Poor Dispute resolution services, Non-existent Call center service

I am not Happy with Experian's service at all. I submitted documentation to lodge disputes against listed accounts. some which i submitted proof of settlement with proof of ID and Address, even got a third party to submit these documents, still today, information still reflect on my credit profile. my score dropped drastically in a period of a month. been trying to call the contact numbers, their call center service is non-existent . these is not good service South Africans deserve.
