Dubious RMCS unsolicited conversion of prepaid line to contract aggravated by disconnection

RMCS, restore my ********** 467 Vodacom prepaid line. On 21 Sep 2017 I asked you to revert the same Vodacom line forthwith to prepaid from your unsolicited contract. I called your offices and was assured that you would do so by one of you rather rude agent (Call Ref#: ********** 255913). Instead of restoring my Vodacom prepaid line you aggravated my situation by actually deregistering it and disconnecting it. This is costing me on many fronts and I will seek legal recourse if you do not redress your improper dealing.
