Terrible Service

I called MTN call centre on 07.10.2015 to query transfer from contract to prepaid ref ***. Agent told me that any Airtime and data I had will be forfeited so rather use it up before next allocation and then call 16.10.2015 to request transfer. Used up my Airtime and data as advised and then called in 16.10.2015 around 4.00pm to request transfer. Pilane told me someone will call me back before 5.00 pm to action transfer because he can't do it. No one called!! Then called back and spoke to Palesa who said that Pilane advised me incorrectly. So Palesa processed transfer request but guess what? I have to wait SEVEN WORKING DAYS for transfer to go through! So why did I have to use up all my Airtime and data? Why didn't the first agent tell me that initially? And now I am having to buy Airtime in dribs and drabs because I don't want my wife to have no Airtime when she's driving AND for fear of losing any Airtime or data because who knows when someone at MTN will decide to wake up and start doing the work they are getting paid for and suddenly I find that transfer is done.
