Phoning a company 85 times in 10 months

I have officially phoned bronberg connect 85 times since March 2019 to complain about being offline or experiencing slow internet speeds. I pay R1000 per month for uncapped 40mg line, so that's about R10 000 for a service that I must phone 85 times to sort out. How on earth can a company be so bad at providing a service that you need to phone them 85 times in less then a year. Totally disgusted. Having to buy airtime especially to phone a company to find out why my internet is not working
