I was lied to about Installation charge

I am very very upset with att.  I was lied to about the installation charge for phone service, so I called and tried to talk with a representative but ended up cancelling  the new phone service    Now I have to pay over $165 for  less than 2 weeks of phone service all bc your representative lied to me!!!  I would love to have someone go back and listen to my conversation with the representative on 2-23-18 at 9:15 am.   If I would have known, I was going to be charged the $99, I would have never gotten the service in the first place.  I was assured that the fee was going to be waived and now that it got installed, I am stuck with the bill
