Contract migrated to Prepaid without consent

On Tuesday, March 08th, i requested a pre-mature cancellation quotation from Vodacom Retentions/Cancellation deoartment which was well received and i'm still considering. On Wednesday, March 09th, my phone was migrated to Prepaid without my instructions, no notice, nothing I couldn't make calls, i cudnt receive any messages, neither could i get hold of my finance who was on the Gautrain and I had to pick her up from the station, neither could she get hold of me for 3 hours whiles Vodacom was playing around with my phone. <br> <br> Finally i figured out that I'm on Prepaid then I called the Customer Care where i was told by Portia (Contracts) that she cannot help me. This was not the first time that Vodacom Customer Careless tell me \They don't Care\" . Magically my phone is now back on Contract and in light of the recent MTN/FNB banking ****s and losses I'm more convinced that I don't want to keep this number no more as it is clear can do as they please and not provide an explanation, then my sim card can be replicated without my knowledge. <br> <br> Please tell me why you added an additional Smart L to my bill?<br> <br> Vodacom, we love your \"best network\" but your customer service is pretty disappointing"
