Vodacom *****s your money! Stay away!

Good day,

I did an upgrade on the 27th of December, for 2 numbers. The contact amount was R99 for each number. Now I suddenly have to pay R301.16 per month? My old contract ended on the 31st of January and I was billed and payed for the contract of the second of January. The new contract started on the 1st of January, however I was billed incorrectly on the 1st of February, I was billed for the old contact (R418.16). I contacted Vodacom and then suddenly my account went up to R531.22. They resolved this issue and credited my account with 2 x R171.01. However, the initial issue is still not resolved. I received a notification from Vodacom that I can upgrade and now (2 Months later) they are telling me I still have to pay my former contracts handset. This is ridiculous! Why would they tell me I can upgrade and then still want me to pay my former handset? This handset was given with the contract package and not a more expensive handset. Every time I contact Vodacom, there is more issues and more ridiculous charges.
