Pathetic service from VODACOM!!!!!!!

I cannot believe the pathetic service I just received from Vodacom!!!!! Firstly I app**** for a Fiber deal to be connected to my home last year in July 2021. This was never connected till today. They gave me an LTE router to use in the interim they said they will give me 100gb FREE to use while I wait. I waited till today for the fiber to be installed with no luck! Now I'm told I owe Vodacom R3999! I have never received a single bill, I DONT KNOW WHAT THIS DEBT IS FOR! after numerous attempts to get help from their pathetic call center I managed to fight to speak to TL (Lindi) who managed to cancel the account and cancel some of the debt I also made a payment for the data I used INTSANTLY. Now all what I'm asking for is to get a settlement letter but no one is able to assist. I spoke to countless agents!!!! I have been sent to Cancelation, Billing, Retentions department they all failed. The most disappointing part is the fact that even the so called TL are not trained on customer service. Asheeka Naidoo and her agent Bathabile are the last two I just spoke to that kept me on hold for more that 2 hours and Asheeka ended up transferring me to department that is closed as she failed assist. I am typing this with hope that I will finally get the help i need!!!!! very ANGRY AND DISAPPOINTED. I NEED MY SETTLEMENT LETTER SO I CAN MOVE ON WITH MY LIFE!
