Terrible service for Delivery

I went into the Clear water Game store on Saturday the 5th December and purchased a Microwave and was guaranteed that the microwave would be delivered on Monday the 7th December . I told the store that the microwave can only be delivered after 17.30 and the store assistant guaranteed that they would deliver after this time. The driver called me at 15.00 after it was already agreed that it needed to be delivered after 17.30. The driver then advised me he was going to Midrand and would be delivering the microwave after that. I've been calling the driver ever since 17.30 and there is no answer or the phone goes to voice mail ! This Is unacceptable! !! A microwave is used everyday and now I'm inconvenienced!!! The lack of communication is unacceptable!!!!! Won't be going into Game anymore!!!
