Pathetic service,staff too relaxed

On the 8th of March i contacted sizwe to register my dependent on the maternity programme. On the 9th Patience called me back and took all the details and told me she has been registered,a consultant will contact the dependent and a baby pack will be delivered to our home .On the 11th another consultant calls and speaks to my daughter,tells her she is covered for 9 checksups-2 x2D scans ,delivery at a network hospital ,this after taking expecting due date and all details and a authorisation code then i emailed size on the 23rd to find out if she can go to any gynae and list of hospitals surrounding us they then respond to my email after 3 days that she is not on maternity program,i need to complete the attached and send to them to which i responded that she was told she is on and even got and authorsaion code,they respond after 3 days again that she is covered from 26.03.21 - 28.07.21(delivery date) My irritation is that they service is so slow and then they give you half info and incorrect information as i made a mistake when i said end July as doctor advised it would be between end June or beginning of July Now how long is it going to take for a response again I want to know if my daughter is on the plan and what is the authorisation codes also,is there no proof of registration with clauses,,,is it merely a word of mouth thing,do i use the same auth code to book a bed in hosp

Please i need proper and full information
