Appalling customer care

I ordered blinds and paid for them on 09 September 2024. They had sent their own team to take the measurements. A team to fit the blinds was only sent on the 02 October. Two of the blinds didn't fit and they were taken back. Today is the 15th October and the faulty blinda are not yet installed. The worst however is the absolute lack of communication with me! And phone calls that are not answered.
