Pathetic service from vodacom and customer repairs center

I booked my phone in for repairs on 05 November 2018 after it was ****** and found it after investigating. In December I made numerous calls to find out the status on my phone as I was promoted to open the new workshop in Mozambique and explained to them I need the phone before leaving to Mozambique, eventually I received an message to say that my phone is ready for collection but by the time I was already in Mozambique. I called the store to explain my situation and asked them if I can make an eft payment to secure my phone, the gentlemen said no I cant make an eft payment on repairs I can only do so If i have a contract to pay and I do have a contract phone but via debt order. On my return last month back to SA I called the store to asked them if my phone is still there and this time I explained my story to a lady and she couldn't pick up my phone if it's at the store or not and said she will call me however she said I can make the eft payment and send the proof of payment to her which I did. I called the head office, repairs center and store numerous times and everyone just say they will call me back and this far no one came back to me, it's almost time for me to go back to Mozambique again.
