No Feedback to Query

I`m currently out of the country, therefor I cannot call them and can only correspond via email.<br> <br> My phone was ******, and I queried MTN on buying out my contract so that I can get a new one. They responded asking me for details on my account which I provided. They haven`t responded since then. <br> <br> I want to get the details sorted before I visit SA on the weekend, so that I can get a new contract, but they simply are to *********** to respond.
