Empty promises

I am very dissapointed. I called the dispensary around 3pm today and spoke to what I assumed was a pharmacist. I explained to her that I am interested in purchasing a walker for my mom and have checked with Bonitas, my moms med aid and they assured me that she has up to R7,000 for walking aids. I asked if the pharmacy could confirm this with the med aid and to make sure there is no extra levies required by the pharmacy. I was asked to give Cheryl all my mom details. When I got home after 5 pm I called again and spoke to a lady at the dispensary. Cheryl had left for the day. She said the only way for them to know if a co payment is required is to process the claim. Once again I told her that its difficult for my mom to move and I would have to uber her up. That's why I want to be sure I can claim the walker on the med aid before I bring my mom. We ubered to the pharmacy just after 6pm and was all excited looking at the walker. Only to have Aamien tell us we had to pay cash for the walker and later claim the money back ourselves from the med aid. I told him about the calls I made to the pharmacy during the day to make sure I don't bring my mom out unnecessary. He didn't even query with the staff to check who u spoke to and did not even check my moms medical aid details. He just kept saying I had to pay cash. My can't move easily and I had to borrow money at work to uber her to the pharmacy. I was given the impression that I could claim the walker on the med aid. But after getting my mom there I was just dismissed without even an apology for the misinformation I was given
