So I have to pay BT due to the mistake of one of their employees? Kindly explain how this works please.
First read BTs Terms and conditions which you agreed to when you signed up.
"How long does a service last and when does it start?
Each service will last for a minimum amount of time (the minimum term), which is set out in your order confirmation. We switch on a service on the service start date shown in your order confirmation. We start charging you from this date too."
minimum term – any initial or later period you've agreed to pay for a service, as shown in your order confirmation.
When a service starts and how long it lasts
These conditions are the same or similar, for all Service Providers.
Your phone and Infinity broadband would have continued to work after your initial 12 month contract, unless you had contacted BT to cancel the service, and paid the £31 broadband disconnection fee.
If you did not cancel, then you would still have been charged. If you subsequently did not pay the charges, then they would be passed to a debt collector and your credit rating would be affected.
You have no option but to pay these charges, as they will get even more as the debt collection agency will keep adding their charges, and will take action to recover the debt.
Next time you take a contract out with a Service Provider, read all of the Terms and conditions.
If you think you were wrongly advised, you would need to raise a complaint with BT. It would help if you can remember on what day you phoned BT, so you can ask them to review that call.
If BT cannot resolve your complaint within 8 weeks (or earlier if BT sends you a deadlock letter), you can take your case to the communications ombudsman.
