Not doing what was promised

Once again Vodacom did not what they said they would. Refer to I-*** sms received 22/6 and I-*** sms received 8/7. Still no refund was made and yet again the debit order was not rectified (another refund) this after the manager confirm that it will be done. Please do not phone me. I'm not going to explain myself again. Your consultants do not make sure of the facts before they phone. Did it with various conversations. Go back to the voice recording in Feb 2021 and the reference numbers and do what was suppose to be done. I am struggling since May 2021 to get this sorted out.
