Cannot cancel

Cannot cancel
I stupidly trusted Three by getting a broadband hub and signed an 24 month contract. I have not touched the thing in 12 months and tried to terminate the contract early. The only way I can do this is by sitting on the phone for 20 minutes before being cut off. They do not accept written cancellations or online confirmations. They send out no reply emails.
If you want stress, Indian Call Centres and no service then go ahead and waste your cash.
I will give you some insight “Smarty” are owned by these people, so if you’ve had a bad experience bear this in mind.
