Airtime reversal

I have previously written a complaint to Vodacom and was contact not long thereafter by a person by the name of Riyaad. Half if the complaint was resolved but as it stands on 23 March the whole problem is not yet resolved. My contract was cancelled timeously on 17 January by 1 March Vodacom had not processed the cancellation and my phone only went on to prepaid on 11 March. Between 1 March and 9 March I had contacted Vodacom several times to try and correct the problem with no result. I am tired and frustrated and so over this issue where no one can assist me and the fact that the airtime was supposed to be reversed and STILL has not been is unacceptable!!! If Riyaad or someone could please just contact me with regards to this matter. As it stands I WILL NEVER recommend Vodacom as a service provider to anyone! And as a business you should know that your customers are EVERYTHING! WITHOUT YOUR CUSTOMERS THERE WILL BE NO BUSINESS! So please treat them as though they matter.
