VODACOM TICKETS NOT WORKING

My sim card was changed from Pre-Paid to contract, after making the change, my whatsapp tickets stopped working . After hours on the phone to sort it out, the problem was still not solved. I went to the Vodacom shop twice to get the problem resolved, in both cases I received a SMS from Vodacom advising me that the query was resolved with ref numbers 1- ********** ********** & 1- ********** ********** , but still the tickets do no work. According to the Vodacom shop, we have to go to the shop several times because each time we log a query it will be escalated to a more *advanced* department. This is terrible customer service.

If Vodacom cannot resolve this issue, I will happily give back the device, cancel the contract to convert back to pre-paid.
