Bad customer service and attitude from Zaheer

My mom is old customer of Home choice and makes her payments from her credit card no issues. Wanted to place an order and was informed that form need to be completed 1st with her credit card details as the info is not taken telephonically, the Home choice policy has changed. Not happy with this mon decided to request me to make internet transfer directly to home choice to simplify as Home choice as bank account with SBSA, FNB and Absa. I bank with SBSA and transfer will go through quicker. Payment transfer was done on the 28t Oct with e-mail sent to the home choice e-mail address [Email Removed] Mom received sms from Home choice informing that payment of the order need to be done by the 30th Oct. She called the call centre and requested to speak to Mark as he dealt with the order previously. Zaheer informed that he does not know such a person and will assist, mom informed him that payment made and need to know why sms was sent. Zaheer informed that it takes 24 to 48 hours for payment to reflect on account. Mom was not happy as this is not customer service and need him to check the e-mail sent, he said did not receive the e-mail, was informed that e-mail is sent to back off
