Dishonored Purchase Agreement

Yesterday I purchased a pair of Logitech G PRO X Gaming Headset from their website that was on a discounted price. I paid the amount displayed on their website and awaited for delivery. This morning I received an email advising me that an error occurred on their website and will not be able to honour the product at the price paid. This is incredibly frustrating and terrible and appalling customer service from such a big company. Needless to say I will never shop at incredible connection again after this incident. truly disappointing from incredible connection.
