Bad service

Last year in August 2024 i opened a phone contract from Blue Label connection and I received the phone but before that I cancel twice but they ignore me and bring the phone I receive it but I didn't like it and phoned them that I don't want it to me ithough is Samsung or Huawei so I give them back so the started to deduct money from my account the one that I gave them up until now they still deduct and when I call them they talk lot of stories that if they didn't get the massage that they get the phone and they say I must bring it like that if ever something missing they gonna charge me and then I agree with them and they gonna call me and tell me until now I'm still waiting for their call when I want to talk to the manager they say the manager will call me so I want them to stop deducting to my account and pay my money back they deduct lR449 every month
