Bad & Unprofessional Services

I have experienced a bad an unprofessional service from Vodacom. Had a data contract and was paid in full on 27th September 2022. I went to Vodacom branch next to vaal-mall Rossini street to request a paid up letter for a personal urgent matter, however was send from pillar to post.

They stated that only head office will be able to provide me with this letter and further said they will lodge a request on my behalf and should expect the settlement letter in two working days. It's almost two weeks and have not received any help. I then contacted customer care to followup and was informed that there was no request under my name. I urgently need this letter please help.
