Innovation Group bad customer service

I took an extended service plan with Innovation Group in 2019 that was to kick in once the dealer service plan on my Haval H6 had lapsed (60000km-90000km).

Today I took in my car to Haval Edenvale for the 1st service under the extended service plan, only to be called by the dealer informing me that Innovation Group have covered got my vehicle details wrong(well the Vehicle Model is wrong) but everything else is the correct information on my car (Registration number, Vin Number all in order.) Human error is acceptable but whats frustrating me is the fact that i have contacted them numerous times asking them to sort and authorise for the service as I need my vehicle serviced today.. After a couple phone calls since 10.30am this morning nothing has been sorted yet.
