disgusted

My fiancee took a contract phone for me at Nashua Mobile Tzaneen in December 2013,before the approval they said we pay R400 that will be refunded 4 months after they've seen that we pay good.6 months passed and we didn't get refund,then few months later they sent a message saying they r closing down and we'll fall under Mtn.<br> our agreement was that we gonna pay R169 until contract expire, to our surprise they (MTN) have been debiting over agreed amount.<br> February they debited R195 now they took R225,<br> what kind of service is this?are they trying to grow their by this nonsense?<br> please!!
