Very bad customer service

Last week Sunday 2.05.2021 spoke to a gentleman at the warehouse at the returns he assist with my return long story short Takealot has 3years it got declined I then told the guy there is a credit note on the TV with instructions what Takealot should do. The gentleman refused to do anything further and told me to take it up with head office. I did take it up with them, I spoke to razinah Peterson, I explained the situation she told that they require a credit note from hisense, I told I have it. She then ask me to forward it to her and I did that and I was told it's going to take 24 to 48hrs for response. I waited, no response up until Thursday evening 6.05.2021 in this time I spoke Lunga keti twice and Ebrahim. I told my credit was not valid because it's not in PDF form after 84hrs. I then had hisense forward the original credit note. And up till now this people really want start this process all today on 11.05.2021 after speaking to the last consultant. The team leaders and returns department are pathetic service givers to customers
