False added fees, and false service delivery. With over promise and under deliver

They add BS charges to your account weekly after you move services to a new address. At least once a week I need to contact their billing regarding new charges that shouldn't be there. They send a courier to come to collect the router for the previous address services and then the couriers just never arrive, eventually after 5 attempts the couriers finally collect the router. and yet they still want to charge me for the router (unused) and add extra fees because there was only enough money in the account to pay the internet fees.
