Cancelation Department has no brains

Asked for a quote to settle only my device...paid the quoted amount and then boom they canceled my entire contract immediately moving it to prepaid. After specifically indicating its a device only settlement and phoning every 2 hours to find out if they acknowledge my email and responses. No replies were given just canceled my contract took all my data and said : Your sim is now a prepaid number.

Fair to say ..I'll move all my business to MTN
