failure to update my details for 5months

I have been requesting for names on my statement to be corrected for almost six months now with no success. I have sent copy of ID and all they say is everything has been updated. The following month when receive my statement, nothing has been changed. I sent a email last week and no response. I sent another one this week to follow up n still no one cares to respond. I never missed a premium in paying my VFA account but dealing with standard bank is like having a subscription that deducts airtime on your phone and you don't know about. Frustrating.
