No customer service

I just got off a call with the most rudest person in the world . She calls her self Lesego

I had a finchoice account that was handed over to them . I then made a payment on the 5th of June 2022 . I was told that I will receive a paid up letter with 14- 21 days but that as always is a lie . Last week I called and I was told that I will receive the letter I should just be patient because it’s not even 21 days . Well I understand because they were still within SLA . Now today 5th July 2023 I call them and guess what I was told to be patient when I voice out that I’ve been patient for a month I was told to hold for the lady who is suppose to assist me , not knowing that I can hear her she says Ohh God hear we go again , I can imagine she was even rolling her eyes. I explained my story again to her but one could hear that she is not interested,she then told me that she will give me feedback today at 3 o’clock , I asked her to advise me what I should do should she not give me feedback and she said and I Quote” Eish I don’t know I said I’ll call you “ Unquote . This is a joke I doubt they even know customer service
