Heidi's grace is not enough for her patients :(

Heidi Nolan said that my baby's nose is shorter than usual. I was not going to do the 2nd test with her but she what's app me insisting on how important the scan is and that she will assist me by having me pay the account off. On my final payment she hit me with a R150 admin fee charge on top of the bill. After emailing her begging to remove the admin fee as I have been in touch with her and I made arrangements with her. She emailed me back requesting that I respect her final decision and if I do not settle the admin fee then the account will be handed over. On her 1st statements she sends she had bottom left of the statement "Gods grace is enough". This dissapeares on later statements. Why use Gods name when her grace is not enough for her patients?
