Envelop Deposit *****

I deposited R10 000 over the ATM using the envelop system because other cash taking machines were not working ( Banks were already closed). The transaction was on (transaction date2015-06-05) on a Friday i received both proof of deposit (bank not and a customer receipt). on top of that on Wednesday a friend of mine deposited R2000 into my account. on Saturday afternoon i received an sms from standard bank that they did not receive my envelop, worse of all they even took the R2000 that my friend deposited. i cant withdraw bcos i have insufficient fund. so basically they charged me R10K plus additional R10K(that actually debited my account) so whatever money i had in the bank i cannot access. meaning on top of them taking my R10K that i deposited they charged me another R10 000. Its been a week and i am so frustrated because i cannot withdraw even the money that was deposited by my friend. i have contacted the call centre several times, and i was told to go to the branch,
