Please fix this as I don't wish to talk about this again

I am supper disappointed with the experience I had when I was collecting my glasses. I went for eye test and finalized everything for my glasses in 2023 April and the medical aid paid a portion of the amount and there was amount due to me that based on the communication we had, and it happened that I couldn't have that amount up until last year around April when I called them to ask how much is my balance the lady that was assisting me said I do not have any balance and I asked if I can collect the glasses and she said yes. I got to Westgate mall I asked again and she said there is not balance and she gave me my glasses and I left for only to keep on receiving emails with statement confirming that I still owe Neo Vision Westgate and when I raised this upon getting tired of these statements the lady that I spoke to on email initiated for me to pay half of the balance. That was their final decision the fact that I was **** to and I was given false information on top of that nothing else is said than getting these statement again. In April when I wanted to collect I had money to pay the balance and I was told I don't owe anything twice in a call and face to face, now it makes it hard for me to even trust doing my glasses with you even though other experiences with you my great but now it will force me to look somewhere else and also I need this to be sorted out correctly. I am not asking you to fire anyone but fix this listen to the call recordings of that day of collection and provide me with the correct outcome for this issue
