Poor communication between ABSA and courier company

Good morning This is really a combined one that includes ABSA and DSV. My mom is to receive a new Credit card from Absa. DSV have contacted me about 5 times - Josiah and Isaac are 2 of those I have spoken to. There was also a woman but didn’t get her name. Also promised to phone back. They promise to get back to me and nothing is done. It has spanned over 10 days now. I phoned ABSA to confirm it is genuine. I was on the phone for 25 minutes and spoke to a helpful lady. I rated her as 10 out of 10 and she said all would be well but since then nothing has happened the last 6 days despite me answering all the security questions. I have power of attorney. I will send this same message under ABSA. They should definitely change their courier company. Thanks Kingsley Stone ***
