Horrible reception and case management never takes calls

I had a wonderful stay at Lenmed Ahmed Kathrada Private hospital at the maternity ward when I gave birth to my son in December 2022 and my son and I were also admitted at the pediatric ward in February 2023 and the staff was helpful. However iam very disappointed by the billing team and the reception. We're wrongfully billed and the is money that we have to pay to the hospital because is was not billed right to the medical aid. When I tried to call the hospital it took me a week to get hold of someone at the reception who transfered my call to the case management department, we spoke for more than 10 minutes while the lady was trying to check what the problem could have been when they claimed. Our phone call then got cut I don't know what the reason was as I stil had a lot of airtime and good network coverage. To my surprise, the lady never bothered to get back to me as she had already gotten all my information. I tried calling back but no one was available to pick up my phone. This is the third week without getting someone to assist me in the phone call. I feel like their call operators are not doing their jobs together with the case management department. Iam very department as this is my nearest private hospital and I was hoping iam gonna use it for future purposes. They seen to not care about phone calls and they are running it like it's a public hospital.
