Arrogant and very much *********** GEMS officials

I am not happy with GEMS, they do not do their work and when you call them to tell them, they shift the blame to the customer. And that made me more furious. I added a dependent on my medical aid last year December. Everything went well, January they called and asked me to sign the acceptance letter and send it back. Which I did, I was communicating with Boitumelo and she explained to me that she will send the letter to the relevant official and that my son is on the waiting period for January but 1st of February all benefits will be activated. That was fine and I received the card on my mailbox. So I took it as if everything is sorted. Come March when I was taking my son to the dentist, the medical aid says membership suspended. I called and lucky for me the same Boitumela picked up and told me that she doesn't understand what happened cause she sent the letter but she will escalate it to the complaints dept or whatever and she re-assured me that they will respond to me ASAP, same day (Ref: ********** 65). I called later in the day the guy that i spoke with said the turn around time is 48hrs with an attitude. Fine I called the following day, they still told me that the turn around time is 48hrs but they will again forward the letter to the relevant official cause it seems like the letter didn't reach the correct person i guess, as to how that happens I have no idea. So yesterday 08/04/2019 I decide to call again, the lady that I spoke with had a very bad attitude, she didn't want to listen to my complain all she kept on saying was its my responsibility to check with GEMS after 48hrs of sending documents. I asked her to check what because I sent the documents and I received a membership card with my dependent on it so whats there to check? And then she checked the acceptance letter that I sent and said the date i wrote when i signed is incorrect, it states 2018 instead of 2019. So I asked why didn't you guys notify me that there's something wrong with the letter? She said I quote "It is your responsibility to double check and follow up after 48hrs". So I asked but the person that opened the letter and saw that the letter has an error, why didn't s/he contact me and say that I must resend it or something. She continued to say it is my responsibility to double check the documents. Meaning that even when GEMS sees the mistake on the docs they will not contact you because it is the clients responsibility to check? What nonsense is that? Everybody makes mistake. So I asked of the way forward because I couldn't stand her attitude, so she said she will forward me the letter again and I sign it and send it back. Mind you the letter that she sent me has a wrong option and a wrong date. So I asked about it and she said I must just scratch the option out and write the correct one and leave the date as is. So if they can send a letter for me to sign with the wrong option and wrong date than why is it wrong if i send a letter with an incorrect date? Anyways before I did that signing and sending back to GEMS i receive a call from GEMS saying they are activating my depended but he is going to be on the waiting period for 3 months. Listen I would understand if the mistake or the error was with me, but now I have to wait a whole 3 months for their mistake? That is not fair at all. They said they received the letter on the 3rd of April 2019, I told them I didn't send any letter that day. Meaning they used that old letter I send on the 15th of January 2019 with the wrong date? If they can use it now, then why didn't they use it then? I am fuming and disappointed at GEMS, they do not know how to treat their clients it is disgusting. I want that waiting period of 3 months gone, I want GEMS to activate my son's benefit and NOT over charge me for it. Your ASAP response will be highly appreciated.
