Huge waste of my time

I ordered stationery (back2school) on 07/01/2018. I have not heard anything regarding this. I cannot get through to the global call centre. I went into the store I was suppose to collect at, but they said I must contact the head office. My call was dropped 3 times when contacting them. Schools open on Wednesday, and I am left utterly frustrated with Waltons poor service and delivery. So much for convenience of online ordering. I would have been better off queuing at a local retailer!
