hello R100 for doing the right thing

im totally appalled by the vodacom collections department and customer care . i called on the 22 march and updated my banking details and was advised my debit wil be successful on the new account . however on the date for debit vodacom debits my old account which then came back returned and charged me fees and R100-00 with vodacom this is unacceptable vodacom messes up and i get billed from the bank and them . then finally wen correctly debited from my std account voddacom leaves out the one new account . please refer to higher management for investigation of this pathetic misunderstanding.
