Appalled by service received from Discovery

I completed a gorm for Discovery in December requesting main membership be transferred to my husband as I was moving to another scheme. Therefore my husband and 2 kids would be the only members on this scheme. This was acknowledged over email and I was told new membership cards will arrive in 6 weeks. All was well until the Jan premium went off ny account. I was still being charged for 4 members. I contacted Discovery and they acknowledged they had made an error. They changed the membership to 3 people after 73min on the phone and advised they would refund me in a week for the additional amount taken. A week later nothing happened. I called again and got off 4 times. Eventually I managed to get through and was told by the consultant that the medical aid was used for an amount of R1900 in Jan and so my refund was taken for this cost. Yes the medical aid was used but by an active member and not me. It was used by my husband and therefore this should have been taken out of savings and not my refund. After another 75 minutes , they acknowledged this was correct and I was told that the claim would need to be reprocessed and then my refund would be done in another week. A week later still nothing. I called once again and got cut off 8 times. Eventually I got hold of someone whom checked the system and found nothing. No claim to be redone or refund. Even the reference numbers I provided made no sense. I spend almost 2 hours explaining the situation and him checking. Eventually I got cut off cause my airtime was over. He called my husband and advised that the refund would be done in another 7 days. Guess what its over 7 days and still nothing. We received an email that the claim was processed on the 11 Feb and payment will be made on the 8 Feb ( which made no sense what so ever ) the amount was supposively going to be paid to me . Which I did not request as the doctors claimed directly from the scheme and shoukd be paid directly to them. All I wanted was my refund for the additional premium taken. Furthermore the amount was R400 less then what I was owed. I have no airtime to call them again and sit for another hour. I have sent messages on facebook to contact me and still no contact. Its been 3 weeks , over 4 hours of my airtime wasted and still no refund for a mistake that was made by you. I am utterly appalled by the customer service for such a big company. Furthermore they took a situation and complicated it to the core where I dont think they even understand what they doing ..
