Mellins Tableview poor customer service

I made an appointment for the Saturday then later received a phonecall to say that they had system issues on their side and there were no appointments for Saturday. I then made another appointment for the sunday. Was promised that I would receive a sms in the morning to confirm my appointment time. I received no sms. So I tried to phone to confirm, I phoned several times throughout Sunday morning and there was no answer. Eventually got through and my appointment was in 15 minutes, impossible for me to make. There was no apology or any sympathy on their side. I am really not impressed with your level of customer service. Sort out your technological difficulties and answer your phones.
