Your level of incompetence is impeccable, second to none

I'm extremely furious about the service I've received from Toyota Financial Services. I took an extended service plan for my car from July 2020. I've been paying the premiums as per plan. I took my car to Foster's Toyota Robertville for service as it was due for a 60000km service on 13/04/2021. I then got a call from the dealership, telling me that my account is on hold and they won't be able to service my car. I then called Toyota Financial Services to find out what was going on, and the response was that I had missed a payment for the month of October 2020 and that was the reason why they couldn't authorize for my vehicle to be fixed. I asked if I could pay immediately at the dealership and the consultant said no, but they will debit from my account on 19/04/2021 and I should bring the car in for service 48hours after the payment has been received (21/04/2021) . They then debited as discussed and I brought my vehicle on 22/04/2021 which is 72 hours after the payment was made and still my account is on hold. First and foremost, they didn't contact me about the missed payment and yet they received my premiums from November 2020 till March 2021, well-aware that my account is suspended. I did exactly what I was told and still not getting any joy. It is because of their incompetence that I'm now coming out embarrassed and humiliated, not once but twice. To the Toyota Innovation Group, fire your *********** personnel or close this division as you're pretty useless...
