Akready sick of them

I am fed up with this company and I just started with them a month ago. I got an lte package that is now refusing to connect and a call center that refuses to answer their phones and sets me up with an Ai to send me text messages or refuses to help because I don't know the phone number. Which BTW Noone sent me. I didn't even get as much as a confirmation of what the lte Sim would be and yet the call center wants to ask what the number is?? I used my ID and email adress in YOUR branches and you didn't have a single complaint when handing out the package and now I can't get hold of anyone to fix the error. Branch doesn't answer phones, call center refuses without a phone number and website gives me a useless Ai bot that keeps asking the same questions and refuses to offer actual assistance. Do you guys believe this is how you keep clients?
