JET/EDCON POOR CUSTOMER SERVICE

I paid all money owing to JET stores on 16 January 2020. I was told to wait for seven days for the money to reflect. I went to collect a paid up letter, I was told to wait for 48 hours, I have been going to the shop every 48 hours but up until now there is nothing. In mid February the letter was sent to a wrong email address. For the tenth time now I am giving a call centre agent my correct email address where the letter would be sent but as I am writing this review I have not received the paid up letter, but a call centre agent promised me that I will receive it before 2.00pm. What is the difficulty in sending a letter to my correct email address, this is not only frustrating but annoying. Can I please get a contact of a relevant person who can help me in this regard as the call centre system has not yielded any results for me. Jet/Edcon has really disappointed me.
