Vodacom not honouring cancellation of contract

In order to cancel my contracts with Vodacom, I have emailed through all required documents (completed Premature Cancellation Quotation, copy of ID, proof of penalty paid) on 27 March 2019 with the agreement that everything would be cancelled effective end of March 2019. I have used the following email address: ***. I cancelled my contracts as I have immigrated as of 01 April 2019 and had to pay a penalty to get my contracts cancelled. End of April no deductions went of my bank account and I thought Vodacom has cancelled my contracts as per my request. May and June Vodacom deducted money from my bank account and as I sit overseas I could not contact them. I have arrived in SA on 26 June to come fetch my dog and my first stop was Vodacom World. So the funny thing is that it is SO EASY to open a contract ANYWHERE, but to get a cancellation you can ONLY phone the call centre and sit on the line for over an hour to sort out the mess..... The end of that phone conversation was that my contracts will be cancelled end of June. Within 2 days someone from Vodacom was supposed to contact me with regards to refunding me for the 2 months that was not supposed to be deducted. I am still waiting.... Also, I cannot find any number to reach Vodacom. Since being a Pre Paid Client, there is no Call Centre service. I was such a huge Vodacom fan, always telling everyone that was battling with their Provider to move to Vodacom, just to be left REALLY disgusted.
