Sending phones aways without notice

I handed my TAB in at the Samsung Smart Centre, when I wanted to collect my TAB there was a notice on the branch that they are closed and we have a phone a certain number. When I contacted them my TAB was at SSS Cellular in the East rand and I am from the west rand. They send me a new quotation as they still did not fix it by that time. After I accepted it, they repaired it. I requested them to deliver it as the east rand is so far from where I gave it in for repairs which by the way the never told me that they will be closing down. After they said they want the payment first, I send them proof and everyday they send me from this one to that one and say they are waiting for Samsung, and I still don't know when I will receive my TAB but the payment had to be made immediately
