Agreed a fixed price 18 month deal on 29th December 2020. Got the paperwork the next day. All done I think. Five weeks later, they write to me telling me that my monthly fee is going up more than ten percent. Ring to complain, thinking it was a mistake, but told no it's not. However maybe they could bend over backwards to offer me a small discount to make the increase a bit smaller but still an increase. And I should tug my forlock and be grateful for that. I don't want a discount on the new price, I say. I just want you to honour the agreement you made. Sorry can't do that they say. Right, I say, I want to raise a complaint. Ok they say we will open a complaint. And what action would you like us to take to resolve the complaint? They ask. Honour the f****g contract we agreed! I cry. Ok they say. We can do that as a complaint resolution action! Terrible customer service.
