Bad Service!!

I am absolute upset at the handling of the upgrade of my data account on the 12/2/2015 I called in to upgrade my data account and order a new Wifi router, I then agreed to have it on back order as they were out of stock. I then on the 1st March noticed the account had not been upgraded to the correct data amount. I then called in (12/3 1 month later!!!), for them to tell me that the upgrade had been cancelled, without a call or notification to myself. I was then spoken to very abruptly on the 13/3 by the Manager who asked in not such a nice way to give them 24/48 hours to get to the bottom on it, which I agreed to. Needless to say I phone back 16/3 to which NOTHING has been done about and I have had to upgrade the account again and wait again. I am disgusted that my query as to who cancelled the upgrade has not been addressed and my account has not been rectified. I have now had to spend more money to be able to keep my data going, I have 4 accounts with you and expected to treated well and not so badly by your managers!!!!! UNACCEPTABLE VODACOM!!!
