Worst customer service ever

I have been waiting now for over a month for a simple paid up letter that telkom has been promising me. I made full payment on the 22 January 2021. I called in to notify them of the payment and that I need a letter as soon as the money reflects. The funds reflected on the 26th January 2021. I have made several follow ups and each week its either speaking to a contact center consultant that doesn't know what he is talking about or another promise that never gets fulfilled. I am honestly so annoyed at this that such a big organization can have so little regard for its customers. I will definitely be taking my business elsewhere after this if this is the kind of level of importance and regard you place on your customer service. If I do not have that letter hy next week Monday I will cause a scene on social media cause I cannot be waiting this long for something so simple.
