Extremely poor service

I took out a cellphone contract with Blue Label Connect. I received a htc Wildfire E lite cellphone in April. Then the phone would not charge anymore. I reported this 3 times already, since October 2021 and nothing was done. The first time I reported the phone, the person who spoke to me was extremely rude and even laughed at me. When I phone the help line they don't pick up or they make promises they don't keep. I don't understand why I should pay for something I am not using. They are very fast to take my money every month, but their service should get 0, zero stars.
