Poor Custer service for a loyal Customer

I have been with my way since 2017 never missed any premiums or submitted any claims,last month's I missed debit order in the 7th I contacted Miway to rectify and change debit date the lady told me they will debit R276,54 emmidiately to cover me from the 7th till 19th June then R365 on the 20th to cover me from the 20th till the 30th as I change debit date.then my normal debit will go off in my newly change date of 30th.i asked if I was possible to debut once the total mount of R636.54 she said yes that will be arranged for the 7th..by the 10th still no debit but I see on their app a debit of R277,54 processed .I decide to contact the again the guy gave me a payment on link and said once payment is done the R276 won't hi off.the link had issues I couldn't pay I went back to Miway to ask for anothe link I was told they can't send another link and can't run a debit order as they need to check what happened on the system so I asked if they going to debit the R636 he said no I ask about the R276 he said no debt will go off..the next day the 11th June a debit of R276,54 came out my account at this point I'm thinking the next debit will be on the 20th for R365 but a debit of RR636 was process and was unsuccessful the enough money for R365 as already R276 was taken .the level of incompetence after speaking to about 4people still no help I have decide to cancel the policy all my money waisted for more than 3years for nothing
