Dreadful Customer Service!

I ordered 2 sets of loose covers for our Coricraft sofas back in August 2020. I was told that due to Covid protocols it would take up to 12 weeks for the order to be completed. I accepted this, paid 50% deposit and waited for the covers. After 14 weeks passed, I contacted the branch to say I needed the covers to be delivered by 1st Dec latest. I was told they would be completed on 3rd Dec. On 3rd Dec I was told it would be another week and that the covers had just gone into production. So it had taken 14 weeks before the work was even started. This was totally unacceptable and I told them to cancel the order. The female sales person in the branch was rude and extremely abrupt and informed me that I would be charged 10% handling fee to cancel. As they had failed to deliver on time I said this was not on. She was very abrupt and rude saying it was just another week! This was untrue as it was now 3 weeks late. The order was not cancelled and I am still waiting for the covers. My husband emailed Corifcraft head office, but they have not had the decency to reply or acknowledge the email. I will not be purchasing anything from Coricraft in future!
