Membership disaster

My husband and I are both separate members of the same medical aid with the same option. We wanted to combine our membership when we got married. Call centre told my husband that myself and my kids would lose our benefits for a month while transfer is done. When I called, I got a different story. My husband sent through forms to add members 2 months ago but the transfer hasn't been done. I sent a follow up mail to them and got nothing more than an automated response to advise they will contact me. I'm currently on maternity leave and being debited for 5 members!! For the last 2 months I have to create money for a debit order that shouldnt be there as we're supposed to be on my husband's plan....last year already but due to their incorrect info we delayed it as the baby was too young to not have cover for a month. Call centre is confused...membership Dept are slack and non-responsive. Very disappointed. Not at all how I've known them. What a total mess.
