London Marriott Hotel County Hall

We were seriously misguided by the hotel. We booked a Duplex King room with room overseeing river Thame and London eye. We were proposed to a room with Big Ben and Westminster when we checked in, the cost mentioned was GBP 100 for this upgrade and GBP50 for breakfast per night and complementary for my daughter. We have confirmed the upgrade and paid. Though later the day we think it would be very rush given our stay is less than 3 days, would be wise to skip breakfast, we called the front desk and they asked us to talk to the front desk, we later appaoched the front desk and asked to cancel just the breakfast and the staff said will reimburse for us. When we checked out, we noticed no refund was made, we talked to the front desk who said the offer was GBP150 per night to upgrade the room and breakfast and no refund would be made. The manager also spoke to us and repeating the same and ignoring us that we were told the offer was splitters between upgrade and breakfast. We are very disappointed the manager didn't try to check further and just firmly said that this amount is only for upgrade and not reasonly to charge for GBP 50 for breakfast therefore she indirectly referring us lying? And if the front desk staff followed up the first day to let us know then we could just eat something if would not be cancelled. We ended up paying GBP500 per night for our stay but the attitude of the staff including the bell boys are rude. We didn't get our room cleaned up until 3:30pm and the bath robes in our room have stain on it. Money indeed worst spent and they keep selling upgrades or other services to each arriving customers What it can be better is they communicate clearly or I feel it is onyy a scam and really disappointed by such a big hotel group.
