Bad service and ********** activities

I called Nedbank home insurance on 26/03/2019,to report a licking basin, they have send a company called C. M. S Construction & Maitanance to come fix the lickage they replaced a flexi pipe for an amount R100 and I paid R500 excess amount which means total amount was R600. 00. We were advised to send the municipal water bill for reimbur*****t to my surprise they didn't pay and they didn't provide the reason. The pipe started licking again on when I called Nedbank to come fix the pipe, they sent the very same company to our surprise they started saying I must pay another excess since is not the same pipe according to their records the company fixed the pressure pipe, I tied to explain myself but I was treated like ****. I requested the recordings they said they will be available within 48 hours even today they were not provided. I have a n oder number *** which shows the service which was rendered, which means C. M. S committed ***** and in turn I suffered the loss so I intent to open a case of ***** maybe I will get attention of the two companies involved. I also intend to shift my accounts to another bank because as someone who is awarded professional(private) banker status I feel disrespected and my contribution to the company worthless, maybe other banks will provide much better service.
