Worst service no followup to queries logged you have to contact them

Worst vuetomer service I have ever experienced and I regret ever taking up cover with Bonitas. The first bad experience was with adding my dependent the consultant was not friendly and I waited for the documents until I ended up downloading them as they were sent the next day. Second incident is I stated on those same forms that I would like my dependent added as of the 1st of February they decided to back date their contributions to 2 months and took the money from my account why when I stated the start date? I sent an email and a ticket was logged( 020222QZD3W0) over a week later with no response I called in and was advised the matter was with Finance and they would call me within 5 days, another week later with no call I called ND and was advised that the finance department would reimburse the extra funds taken within 5 days. It's has now been over 2 weeks. I sent an email to follow up only to find my unresolved case was closed and I was issued a new reference number (250222Q0H503) As I no longer had funds to call I used their whatsapp hat function I was connected to an agent by the name of Denisia and I probed all the information including the reference numbers that was on the 28th of February 2022 Denesia said they checking the refs and would get back to me in a few minutes several days later I am still waiting. Worst service I ever had in my life.
