FNB first bodyline insurance scratch and dent

The consultants that works for FNB first bodyline insurance( SMART underwriting managers) are very *********** at what they do because what the policy says and what the consultant does is two different things, i put a claim through for mag repairs with the consultant name Sonia on the 12-October-2020 and she advised she will send me a sms with a email address and i should post pictures of the damanged area, eventually she did not send me the sms with the details i had to call back and a guy name Frederick sent it same time, i also advised both of them that i have a service provider that i have choosen which is krazy wheel customs which i am comfortable with and the job they do is excellent and i also advised them i will send a quote through to them as it will be in the credit limit of what the policy covers, the next day without my consent they got it approved with a company of the name of streamline repairs which i have never heard of i have told both frederick and Sonia on mail that i clearly wanted the service provider that i have choosen and coudnt you understand that? i then sent them a quotation for the service provider that i have choosen on 13-Oct-2020 and today (16-Oct-2020) Sonia sends me a mail saying my claim is referred to tiger wheel and tyre which is completely off from what i asked for its past 48hours which is the turn around time for approval and they still doing the wrong things and giving me the run around..........i had this policy for 2 years now and this is the 1st time i have been so dissapointed with these two *********** consultants and when i took this policy in the begining the consutant who sold me this advised me i can use any service provider that i feel satisfied with as long as its in the cover limit which this is i would like this matter to be investigated throughly and i want feedback as to whats going on.
