Angry and fustrated

i am totally upset with the service of standard bank i had mailed them in feb for a settlement letter after which Leshapa Neo sent it to me after that time i sent her numerous mails regarding banking details , also i had called the call centre because i need to cancel the top up on my premium , they gave me an email address which doesnt even work , maybe i got it wrong i have emailed Leshapa asking for the correct address for days and i have still gotten no response . There service is perthetic and fustrating aside from being pushed from one peron to then next and holding forever. i need the email address to cancel the top up on my premium.
