I sent in my cellphone a week ago still not back

So this is my second hello peter with regards to MTN's service.<br> <br> My claim, which took a week to log, was approved and my cellphone was picked up last week Wednesday to go in for repairs.<br> <br> I have emailed twice to see what the progress of these repairs is with no response.<br> <br> I have phoned the call line, and the automated response for the progress of my claim says my phone is still waiting to be delivered to a repair service.<br> <br> Please can someone assist in speeding along this process? I do not want to wait another week before I get my phone?<br> <br>
