FAILING TO PAY MY INVESTMENTS OUT

I tried to cash out my investments online and i was advised to do it in the branch and i need to bring my ID. in the branch they said i needed a bank statement from the bank as much as i was asking them to pay me on the same account the debit every month, went back in again did the transaction and waited for 2 weeks. i was worried then i phoned head office. they failed to help me, phoned the branch they also failed to help me. I took time off work and i personally went to the branch, i sat there for more than 30min and they still failed to help me. they are still debiting my account as well, i have emailed and called head office more than once but they failing to pay my money back. i made this claim more than a month ago and nothing has been done about it. I just need my money,they busy trying to sell me their new card but they cant process my claim.i wait on the phone for eternity because their call centre is useless.
