Negative star,horrid service provider

If there was a negative star that would be my selection. Pathetic service as usual,unfortunately the only fibre option in my area. Firstly it took 5 weeks to to inform me I need to make a deposit to secure a fibre contract,but don't supply banking details.I called the contact centre who transfered me from pillar to post for over an hour,each person was rude,abrupt and unhelpful. Speaking in a manner as if I don't understand English. Shouting at a customer like you speaking to a child is horrid and disrespectful. Wish we had more fibre options so we don't have to deal with a ****py service and ****py network
