Back in February I had a Live Chat with a BT representative who offered me a £15 a month reduction on my BT Fibre monthly cost. I accepted and assumed it would start after the next bill. This hasn't happened and I'm still paying the amount I considered far too much.
Now obviously due to COVID-19, BT aren't operating their customer service as per normal and I can't contact them to explain the situation. I don't want to phone as I'm not a vulnerable customer.
Also is there any chance BT will refund me the amount that they are over-charging me?
did you get a confirmation email of your new terms/contract?
Was is a definite contract update or just a quote? If the former you should have had a confirmatory emaill, if the latter that's why you are where you are now. Either way, a call to 0800 800 030 should move you forward; it's the only way but you may have to wait a while to speak to an agent.
