LATE deliveries and NO perk points recieved when you shop

I have done three different orders with cotton on in the span of two weeks, and I can already let you know that I only recieved one of those orders on Saturday, about 8 days later and have still not received an update on regards to the others two orders. Also, I had not received any perk points for those three orders made. Usually you suppose to recieve points when you order, once the order leaves the warehouse. I usually receive these points the day after I placed my order, however, as I said I have not received a single perk point in 14 days. I am a big supporter of cotton on and 90% of my clothes are from their company so it hurts me to do this but it the only way. Customer service SUCKS, they are just TERRIBLE at getting back to emails. They either need to replace their staff or train them sufficiently.
