Disgraceful service at Orpington branch. Howdens designed our kitchen, which was fitted by my builder summer 2018. We decided to return an unopened bespoke corner larder unit costing ~£900, in exchange for two cheaper standard tall tower units cast/frames only; as we had kept back the 4x unit doors and had spare hinges etc. to fit the doors on the replacement units. However, Orpington branch have since invoiced me for an outstanding balance on the account; which they are unable to explain what this charge is relating to. I have called the kitchen designer on multiple occasions to go through the kitchen build and the bespoke corner unit that was returned; only to hear time and time again that he is unable to explain what has happened and to leave it with him; for him never to call me back with an explanation as to the precise charges still outstanding. I have visited their branch to return unused hinges and flooring etc. which reduced the initial balance invoice from £770 to the £500 remaining balance. I have written multiple emails detailing my investigation and raising questions; only to have them completely ignored and receive yet another demand for the balance. I have meet with, called and emailed the Orpington branch manager; who’s customer service manner is aggressive, she fails to listen to her customer and pursues her own agender; ignoring all valid questions raised and threatens legal action for non-payment. I do not know if they have double charged me for those 4x standard kitchen doors and I cannot see how 4x standard kitchen doors from the original bespoke corner larder unit would cost £450. I also hope that Orpington branch has not charged me for extra deliveries for damaged or replacement missing kitchen items; which would be grossly unfair. This has now been ongoing for 5 months and I have not received a satisfactory answer, explanation or balance settlement cancellation notification. We have returned every unused, unopened item but still Howdens at Orpington can not explain their additional invoice charge; if anything the 2x tall tower cast/frames would have been considerably cheaper and so I should have received a refund but even this costing for the replacement, Howdens are unable to provide an answer to. I feel I have no choice but to highlight Orpington’s branch appalling customer service and my treatment on this matter. I also emailed Harriet at Howdens social media email address about this matter and have received no call or email in response to this disgraceful matter. They have not only lost our trust but ours and our builders future custom.
