Contract ending - last instalment needs to change

My contract ends on 12 Nov. I see my last debit order is for my normal full installment of R438.50, which will run on 31 Oct.<br> <br> At the beginning of my contract, I paid a pro-rata amount for the Smart S allocation because I started on the 12th of the month. As I would like to convert to prepaid, I would prefer to receive the Smart S allocation up to the 12th only.<br> <br> In other words, at the start of the contract where I paid only for the remaining 18 days in Nov, I would like the reverse to happen now i.e. pay and have access to the portion of data/mins/smses for the 12 days until my contract ends. <br> <br> This means that my debit order should be R200 (last handset installment) + % Smart S for 12 days. <br> <br> I tried to log this through the vodacom website email, despite multiple attempts from different browsers, the \Send Email"button does not seem to work. Please can someone call me once this matter is resolved."""
