Vodacom blatantly **** and I feel ******

What a joke. I've been a clue t of their for o we 15 years and I feel like I'm being ******. I was called by Vodacom and told that they are offering me a special on my contract for being such a loyal customer for such a long time and they are reducing my monthly contract fee to R175 and they are giving me free 5gigabyte data per month. I told the lady over the phone that I don't want anything or more costs to be added to my account but if it's for free I'll take it. Vodacom confirmed that yes, no extra charges, it's an offer for being so loyal. Now I have an EXTRA R175 billed to my account for 5gigabyte data. I called in and I'm told that I must pay it and query it afterwards...honestly, how bad can your service be? Can't wait to switch to another network which will be soon. I wanted to order the fiber also, but I guess I'll cancel that and rather go with a trustworthy provider that doesn't blatantly lie and make you as the consumer pay for it. Well done for lying and robasically robbing me Vodacom. Congratulations to the consultant also for just lying to get a commission, well done...
