Can't get through to MTN!!!!!!

I have been trying to call 808 to speak to the retentions department, but every time I call I am on hold for about 4 minutes then the call is dropped<br> <br> Once I was on for about 6 minutes before the call was dropped<br> <br> I need to change to prepaid but with the way MTN doesn't seem to want to take my call, I don't think I want to stay with MTN.<br> <br> I have been with MTN since 2002<br> Always a loyal customer<br> But this call centre is absolutely nonsense<br> <br> I need to switch to prepaid before the 4th of August!!! Argh!<br> <br> The contract is not under my ID, it is under my father's, but it is still my contract which I want to change to prepaid
