Terrible Service

First off the online system is not working it won't link my card I have phoned and emaiI numerous times but no one seems to be able to help me. I phoned in again and explained that I wanted sleep wear which is online whereby they give 25% but at the store they don't. I was told I could go to Mr Price Bayside and get the item @ 25% discount. When I went to Mr Price Bayside Mall the manager was not very helpful he said that Online must phone him to say that I can have discount, I explained to him that the online app is not working for me and it's not allowing me to link my account . I am very disappoint in the service received via online and at the store. I have had this account for many years and they have no problem in treating the customers like "****", at the end of the day without customers all the stores will close but they don't care.
