Bad Customer Service At Rochester Northgate Mall

i did a laybye with rochester northgate mall for a lounge suite. on 20 February 2019 i went to do a payment and i told the lady who assisted me to please put the order through as heard it needs to be manufactured. i told her please put the order because on the 20th of March i will come and pay the remaing balance and collect my order. she assured me that my lounge suite is always available in stock so i need not to worry about pre-ordering, she even checked on the system and assured me that this suite is always available. i came back to the shop on the 20th of March to pay of my lounge suite and collect it but i was now told they need to put an order through for them to be manufactured and i was told it will take 3 to 4 weeks. i recieved a call on the 18the of april and told my suite is not yet ready they will only know the following week what will be the status of my lounge suite. This is unacceptable and poor service as it is an inconvinience for me. i am really disappoint by the level of service i recived at Rochester Northgate
