Bad service

I called customer service center Lewis group on the 11th May 2022 at about 16:55 to ask for a simple Settlement Letter the lady who unswer the called said she didn't even want to hear why im calling, she just said there are closing at 5pm I must call in the morning and drop the call. And last week on the 12th of May 2022 I called again and they said it will take 2 to 3days they will send it via email. I even send and an email to *** za on the same day but still nothing. I called today wow it was bad they keep transferring me to one another and drop calls I have to keep calling again and again until I have to ask them what kind of service they give their customers then Jadine assist and said the was something wrong with the email she will ask them to send it again. Yhooooo what a drama a full movie.
