FNB not refunding incorrect billing

DISGUSTED WITH SERVICE!!!!!! I filled up my car at BP on 30 of MARCH. they incorrectly billed twice on 17 APRIL. I called FNB and the call centre agent said i must contact the vendor(BP). According to their Standard Bank rep(Hajira Ebrahim) the file for the refund was sent to Angelique at FNB on the 23rd of April. To date i dont have any refund back into my bank account. The telephone number for Anglique just goes to voicemail ***. I have to call and follow up everyday and everyday the vendor( Yolanda at BP Tygervalley) tells me tomorrow it should reflect.<br> <br>
