The whole process leading up to our order was supported by Shanade, she was very helpful and was very quick with her responses. I had a quote from Rhino Aluminium with 24 hours, whereas it was weeks to receive quotes from other window suppliers. The windows arrive on the day expected and were fitted the same week. We then experienced a few issues where the windows were missing a lock we asked for and a hinge. I contacted the Dispatch & sales Manager, Paul, and he sent out the missing parts straight away. We noticed the glass panels had a few defects. I contacted Paul again and he arranged for the window panels to be replaced. The only downfall is the labour to fit the replacement glass panes is at our cost, but it does say that on their website - 'Rhino Aluminium do not offer compensation when things go wrong, we correct the problem which we consider to be the responsible thing to do. Rhino Aluminium do not take any responsibility for any financial losses incurred as a result of a delay in the delivery of an order, or costs incurred due to the replacement of glass units or parts of the products ordered' Over all the windows look great and the Customer Service from Rhino Aluminium was second to none. Even though we had a few issues I would recommend this company and would purchase windows with them again. I would have given 5 star but gave 4 because of issues.
