Terrible customer service - *******s

In the year 2017 i had two accidents involving my vehicle , during the first accident when i contacted standard bank initially they told me my excess was R4000 , the second time i contacted them they said the previous person whom handled my claim gave the wrong amount and the actual excess was R13500 , please not that this accident which occurred in May last year was not my fault but i paid the excess anyway with the condition of being told that i would get my excess back from the third party involved. It is now the 9th of January and i have not received my excess back and that is not the only under handed thing they have done , when my car met the accident they told me they will put counterfeit parts on my car yet i have no record of any mention of that when i took the policy or in my policy documents that they had sent me , upon putting these parts it decreases my cars value yet they still increased my cars insurance , secondly during the first accident i had asked them to add vehicle hire to my policy and to decrease the excess and when i met my second accident they told me i dont have vehicle hire on the insurance policy, and again in this second accident which occurred in December they refused to put authentic parts on my vehicle not because of the 5 years now they saying the vehicle is out of warranty and they are still charging me an excess of R13500 i dont even have that money because i never get back my excess from the previous accident! I will never recommend standard bank insurance to any one they are a bunch of *******s who take your money and give you pirate parts on your vehicle
