Pathetic service !!!

I'm seriously getting annoyed with yall's service, I called yesterday after I got an email from you that a claim was processed on my Nedgroup medical aid card. I requested yall to block the card yet I received another email stating the claim has been processed !!!!! this is unacceptable. I called ***** yesterday and they took down my details and advised that I would get a call from yall.. No call yet !!!!!!! I Spoke to a lady by the name of Ndalo at ***** ref number is: OBH ********** 18 I EXPECT YALL TO BLOCK THOSE CARDS AND PROVIDE ME WITH NEW ONE'S WITH A DIFFERENT MED AID NUMBER!!!! I EXPECT A CALL BEFORE THE END OF BUSINESS TODAY MEDAID NUMBER IS ********** 7908 I WILL ALSO BE SENDING THIS TO THE MED AID OMBUDSMAN !!!!!!!!!
