Bad Customer Service

The Wynberg store here in Cape Town have very poor customer service and are rude. They promised my dad that they will refund his premium. Last month they advised him to pay the last installment and then he is done with those particular products which he then did. They still went ahead to deducted via debit order instead of sending an instruction for it to be stopped. When he went to inquire they said that he can come on the 9th to collect his refund. When he got their they had stories and dad gave the phone to the lady who assisted him to explain to me. She said they will call dad from the 10th and 12th latest as that is whens their refunds are finalised. Today day asked me to call them as they didn't call him to go and collect his money, which i did as he always asks me when they give him problems. I then called and I explained to the lady what the lady told me and dad about the refund and dad still didn't get a call. She had quite an attitude,I then told her they only provide customer service only when one goes to hellopeter and she had said I can go onto hellopeter. Firstly it was their error in not cancelling the debit order and now they have an attitude when it comes to reimbursing the customer their money. She then even dumped the phone in my face while I was still engaging with her which shows there is no utter respect for people even though my dad is the customer, he requested that I call on his behalf there is no reason to be rude makes me wonder how she handles her customers after a sale is complete and after customer service.
