DOUBLE DEDUCTION

can't get through to speak o a consultant. African bank did not stick to debit order arrangement and has deducted from my bank account this month double the instalment due.' I've agreed to pay tn amount of r2789.00 and they 've deducted R4220.00 which has now left me with insufficient funds and with no money to live from for the rest of the month. There is also no response from the telephone number I've been phoning and it 's just voice automated. This is urgent, I need the money to be paid back in my account(the portion tat had been ****** by African bank), this is ******* to deduct more than what we've agreed upon and I still have other bills to pay including.
