MVIA Bad Service

Never have I used an insurance company as bad as this one before. Last year January I took my car to the dealership I bought my car from for its first service after the 3 years warranty expired and I had insured my service with MVIA long story short they processed the invoice from the dealership late to a point my car was retained by the dealership overnight and I was working night shift at the time I had to use my car to go to work so I had to make other arrangements to get to work which is far from home. This year the dealership turned me out and they were not willing to work on my car if I’m going to use MVIA as they removed them from their merchant list because they offer bad service. I then had to call around to get a Mazda dealership that has them on their merchant list, found it and took it there yesterday 05/01/2024. When I got to reception to fill out paperwork the minute I mentioned MVIA the lady at the reception cringed and I asked if she was okay she told me that MVIA is slow when processing invoices and it makes it difficult for them to get people’s cars serviced on time. Then again yesterday I got a call from MVIA asking me to make arrangements on a missed payment and I was shocked because I didn’t miss a payment they’re the ones who short paid themselves from my account they only debited R25,00 which is the tyre cover and not R355,35 for the whole premium. I told them that I’m not the one at fault here why am I the one making payment arrangements now and now they’re going to affect my credit score with their mistake. Again I’ve been calling them since November 2022 to change my debit order date from the beginning of the month to the 15th but it was never done or I’d call them and I’d get a rude operator who would tell me that they’re system is offline I should call back the next day and when I do same story but last December I was able to get them to change it as from this month now they’ve short paid themselves from my account and blaming me for not paying. I’m livid to a point I am going to cancel the insurance because I don’t need such stress in my life, I’ve got enough stress as it is.
