Pathetic Vodacom

So I have a few complaints! (1) Received a notification to use 135 instead of 111 from 24 March - I phoned 6 times 3 times each number it either keeps "dialling" or I get cut off after listening to a prerecorded message with irrelevant info. (2) Keeps getting cut off during a call (mobile phone) or thrown off internet (modem). Two different devices and numbers. This has been going on and off for more than a month! (3) So Vodacom phones and what happens - the line is so bad he cant hear a word I am saying. (4) My airtime on my data card disappears. There is enough data so the airtime should not be lost? ((5) Vodacom assistant was helpful - but still got cut off after talking on a 3rd device? (6) my daughter's phone was given in for screen replacement 8 days ago. I have an insurance through vodacom. 8 days - no call and no sms to say what must be paid or when the phone will be ready. went to the shop where the phone was handed in yesterday. was given a don't care shrug and the person was looking over my shoulder at the shoppers going past instead of in my face. Didn't even bother to take my detailsor check on the system or file. sorry 2-3 weeks. they wont bother phoning i'll get an sms when it is ready. when i took out the contract i was told repairs take 7 days not 3 weeks! Pathetic! Then I get called sometimes even twice a day to ask when am I going to upgrade??? Really?? I think not!!
