Disgusted customer services

I am disgusted by the service that I had at Parrow Centre.The staff was very unprofessional,didn't even ask if they can assist me and made me feel very uncomfortable as they were all standing by the till giggling and staring at me.If you don't know how to treat your customers then this isnt the job for you.I would like get a hold of the manager and raise a formal complaint.I will not leave it like this I feel sorry for the other customer's that don't deserve this sort of treatment.I am very disatisfied and won't stop until they apologize.
