can someone competent enough help

On the 01-06-2019 i did an online upgrade, i subsequently called in twice and requested for the order to be cancelled as i will wait for the June 2019 specials and see what Vodacom has on offer. Please also note that on these calls to cancel the order i asked for the agents to email me or advise me what specials are available for June and they cannot assist. Today i log on and start to chat to Zodwa Una whom i asked for her to confirm that the order is cancelled and she said No, yet i called twice to cancel the order. I also asked her to advise me what specials are there for June 2019 and she tells me to go online bearing in mind that when i select the upgrade option online the system recognises i have already done an upgrade as you have not cancelled it so i cannot see the specials I than ask her to cancel the order and she tells me she cannot i must call in, not taking into account that i have already called twice to cancel the order

Can someone please help me, someone competent enough * I need to cancel the current upgrade * I need a list of the June 2019 specials * If you do call me you have to use my prepaid number as the number on contract with Vodacom is a WIFI router and it cant RECEIVE calls
