Untrained consultants giving incorrect information

The worst service ever , no improvement whatsoever . I called customer care my account was in arrears , more than one consultant confirms that after settling the arrears I can upgrade my device. After paying this at the store to have it reflect immediately with the advice given by the consultant telephonically at the store I am told you cannot upgrade .Anyway good riddance will never ever take up a new phone with Vodacom ever the experience is a total nightmare.
