No internet access

I wanted to cancel my contract more than a year ago for my tablet and was advised to take out a data contract. I took a data bundle as an upgrade for ***. The internet did not work and I called the Customer Services (CS ) desk who advised that the internet was not activated and they activated it, .I still could not access the internet and called autopage various times since then in vain. I have tried GloCell and the agent mentioned that a technician will call me back and no one did. I logged this on their website and received a notification that my ticket has been closed. I still do not have internet and am very frustrated. I have been a loyal customer for more than 10 years. I would like to be reimbursed for the funds/ data that I have lost due to incompetence on your staff. Cell no ***, LL ***.
