TIRED OF VODACOM'S NONSENSE!!!

I do not know how many more ways I can tell you that I am SO tired of this nonsense. I have logged so many complaints but it doesn't seem to help. For the past 3 months I noticed that I don't receive my data anymore. (I have a contract phone where I receive R200.00 airtime and 250mb data each month. We have wifi at home and work, so I don't feel that I need any more than what I receive.) I logged a complaint on hellopeter, and only about 3 weeks thereafter, I received a sms from Vodacom, saying that my package doesn't include data. AFTER I HAVE RECEIVED DATA EVERY SINGLE MONTH BEFORE?? Then, when I checked my airtime balance, all of a sudden, I received 2gigs of data (Which I haven't purchased). After that, I have received my 250mb data again every single month. The last month, randomly, my airtime and data just ran out. I hardly make calls from my phone, and as mentioned before, we have wifi at home and work and mostly every where I go, so how did it just ran out? This morning while at home, I purchased R30 airtime, and of that R30 airtime, I purchased 30mg data, because I know I will receive my data and airtime on the 1st of May. Literally after putting my phone down and making me some coffee and checking again on my phone, I receive a sms saying that my data bundle has now run out. HOW??? In Literally 5 minutes and while being on wifi, my data just "ran out"?! I AM SO TIRED OF VODACOM TAKING MY DATA AND AIRTIME JUST SO THAT I CAN BUY MORE SO THAT THEY CAN TAKE IT AGAIN!!! I am now considering moving to another cell phone network. This can't keep going on like this. PLEASE DON'T EVER TAKE OUT A CONTRACT WITH VODACOM!!!
