Bad customer service

What a bad experience Im receiving from telkom. I settled my account 2 weeks ago and I was informed that I would receive my paid up letter in 7 days till today I haven't received anything. I called yesterday requesting to speak to team leader and I spoke to a guy named Menzi and he said I should be receiving the letter or updated statement today.. Still waiting I sent him an email and he did not respond till now. I've been speaking to different consultants regarding this and they all been telling me different things. I'm very disappointed.
