Terrible Service The Glen Mall Foschni

I bought a cellphone online and due to the parcel arriving late I had to change my plans, I asked that you don't deliver the phone anymore and I was told it has already been dispatched, I must collect it and then return it to any Foschini store unopened for a refund. I collected the phone and I returned it to Foschini The Glen Mall. I cannot express in words the rudeness and bad attitude I received from the two ladies at the till, they further called the supervisor who was also not helpful and blatantly refused to take the cellphone back. I have not even opened the packaging. I need to take this cellphone back as I don't need it anymore and I don't accept the service received from The Glen Mall. Please urgently sort this out.
