Virseker the worst and most expensive insurance

This Company is the worst. Annual increases are ridiculous and I started of with a premium of R724 in Oct 2018 and ended up with a premium of R1370 in Oct 2021. I finally had enough and managed to get a new policy at a very reputable firm for just over R880 per month and with more benefits! I had my comprehensive insurance with Virseker, but also had the "Stampvol"policy all under the same policy number. I managed to cancel beginning Oct 21 after a struggle and after they first tried to convince me not to cancel. However, finally on the 20th of Oct I got confirmation that my Policy was cancelled. End of October the "Stampvol" premium of R196 was deducted (please note that on my policy doc the "new premium" is supposed to be R165.14, so not sure how they ended up with the R196/R254 in the first place). I reversed it on my banking app, costing me R7 for the reversal. I the received a sms to warn me that I might not be fully insured due to the non payment of the amount of R254. I mailed them the confirmation from them of the cancellation and also told them about the discrepancies in the amount. No one got back to me. End November another premium, this time for R254 was deducted. I once again reversed, mailed, etc. Received same sms. End December yet another R254 was deducted, however, I did not manage to reverse this instalment. I then e-mailed them on the 4th of Jan and again on the 7th of Jan. I asked for the instalment to be paid back to me and for confirmation in writing that this policy was cancelled and that there will be no more deductions. Nothing!! So dishonest and unhelpful. I am so disappointed and will never recommend this company to anyone EVER! I cannot deal with companies who sends automated responses on your mails, but never get in contact with you!
