Pathetic Customer service and delivery

My mom suffers from Major Depression and Anxiety due to chemical imbalance she cannot skip one dose of medication without her days turning into one major panic attack. Due to her medical aids choices she has to use Pharmacy direct. Her monthly medication has been on its way since Tuesday 29/10/19. She then received an SMS stating delivery will take place on Thursday 31/10/19 this was day 2 without medication. Pharmacy direct never delivered their Bull**** excuse there was no one to receive the parcel, at a company address!!!! She was at work all day. This morning 01/11/2019 I called them and spoke to a manager Handley(spelling) who informed us medication will have to be delivered after hours tonight. I told him I needed a telephone number to contact if we do not receive medication he gave me a cell phone number by 19:00 guess what.... No medication.... 7 phone calls no answer he does put the phone down though... Dealing with my mom going through another panic attack, that she can't come out of because of the thought that she will have no medication for the whole weekend. Medication arrived 10minutes ago (thank God). This so called manager phones my mom to say your medication has been delved, she says thank you for answering my calls and keeping me inform (sarcasm) he says its a pleassure and hangs up. This is absolute pathetic customer service from a company that deals with customers that rely on customer service and on time delivery. All I can say is atleast me moms situation was serious but not a life or death matter, otherwise she would have been dead and who would have taken responsibility then????
