Delayed medication poor service delivery

My parents medicine has been delayed numerous times and it is affecting their health and routine of taking their medication. We have been complaining and reporting this problem and have been promised that it will be fixed but to no avail. Pharmacy direct have sent the bill request and it has been always so that the medication can be dispensed but we are still awaiting the medication. I am deeply concerned for my retired parents health and it seems it is not being taken seriously by pharmacy direct. I am seriously thinking of taking this matter to the SAPC to resolve this matter my parents have no knowledge and depends on the pharmacy to deliver on their promises, how many other people have this been happening to you. What more do we have to do to get our medication and what did we do to deserve such poor health service. We depend on pharmacy direct to assist us because we go to our doctors appointments get scripts as requested by pharmacy direct but still a delay in medication. Please help I do not know what to do anymore.
