Unauthorized Capitec Credit Facility

Capitec Bank has offered me a Credit Facility (Temporary Loan) of +- R3000. I do not need the facility, so I did not take it, however whenever I try to apply for any other credit facility with other financial institution (in this case MTN) I do not qualify due to affordability - which is worsened by the "credit facility with Capitec" I visited Jubilee Mall branch and was assisted by a consultant whom informed me that she is declining the facility so it does not reflect on my credit profile. I just checked my profile again with transunion and the facility still reflects.
