BAD BAD BAD CUSTOMER SERVICE!!!

Firstly i have been a loyal client with Miway insurance, my car was damaged and i logged on to your website to register a claim, the website then asked me to update my personal details (Contact number & email address). After updating my details my premium increased, how do my premiums increase by updating contact numbers and email address? Then i contacted your call center to register a claim. I advised the consultant that i wanted my vehicle to be repaired by Success Panelbeaters, she advised that it will not be a problem, 1 week later i was informed that my claim was approved and an assessor would contact me shortly, no assessor contacted me, i had to call Miway again and this is when i found out that my panel beater was changed to FNR Panelbeaters. Why was this changed without my knowledge especially after being advised by the call center agent that my vehicle would be repaired at Success Panelbeaters, Miway then advised that i need to sign a disclaimer form and they would pay the money into my account, to my dismay Miway wants to pay me R2526.56 for damages quoted at +-R16k, how do you expect me to repair my vehicle with such a low sum of money? This is pathetic service
