Bad service

I was so happy with sixty60 right from the start, good delivery times and and very little times the Centurion shop did not have in stock what I ordered. Since 2 weeks back I can not get any beers, ciders and other liquors except wine and a above average of what I order on groceries is out of stock. I called the help centre and was told that my account was moved to Castle gate shop and they don't have a liquor shop so I can't order any other liquor except wine. They don't have any answer for the rest of the out of stock items and won't move my account that I used on a very regular basis back to the Centurion shop where I was happy to do business with them. It is pointless to me that I must use an app that can not supply me with my regular orders like in the past. Please move my account back to where it was. Hope to hear from you soon.
