Complaint, terrible customer service

Worst experience with the contact centre and store consultants and managers.

I called in to the call centre 24 hours after I did an upgrade at the gateway store asking to cancel the contract that I have done as I no longer required the expensive contract, they couldn't retain me so they said I can return in store and call in to cancel the same day. I called the centre yesterday they advised. So I went into store today and they said they don't do cancelation they don't have a cooling off period. Which ****** company under legal law doesn't have cooling off period, I don't want to have this anymore and want to cancel. Please can someone sort this out, I will not pay contract fees and if the contract doesn't get canceled I will remove my banking details and get a lawyer to further address fhis
