Worst service

This is worst company insure experience I have ever had, I spoke to constantly in July 2021 , where I requested to change my debit order date to 1st of every month and also to see if they will give me better premium since the current premium was extremely high. August came it worked fine and debited me a pro-rats fee, then September comes the debit order date changes back old the date and the premium changes.So I phone the retention department on 26th of October 2021 to find out what happened now so I spoke to Gugulethu Khumalo, who advised that they will revised my insurance premiums to low price and that they which credit my account from 1 September 2021, change the date and my banking details to new account details. However I will have to pay pro-rata again. I phoned Gugulethu Khumalo on the 27th October 2021 to find out if it was sorted and to remind her that I never receive her email that she was supposed to send me since 26th of October 2021, so confirm everything. She was supposed call me back to confirm in details, the credit shortfall and discovery will debit on the 1st of November 2021 .I email her again on the 29th of October in morning asking for an update, which I never received to date and then I receive a letter from Discovery to state that my debit order never go out on the 27th of October 2021. I forwarded her email and asked her to call me urgently up to date I never received a call from her.I phoned the call centre again an l was told that they was error but they submitted everything 27th of October.So my account will be debit on the 1st with the new premium and I asked for manager to call me which she did but she said she will request the retention manager to call me. I never receive a call from the manager to date. I see on the 1st of November the pro-rata amount get debuted only. So I assume they will debit the account during the courses if the Month. Today the debit order goes of but with old premium. I cannot understand what happened yet I phoned so many times to make sure all my information has been changed, since 7 years ago I was paying for information that the sales constantly captured wrong. That the reason I called numerous times to make sure everything is updated but still it did not help!!!!!!! I guess this is Discovery’s new type of service?
