Pathetic Vodacom follow up

So I got 3 calls from Vodacom after my complaint on hallo Peter. However In the 1 hour I have been on internet this morning I had to reconnect 4 times - this means the issue has NOT been resolved and although the personnel at Vodacom is very accommodating Vodacom is really starting to annoy me with their bad signal!! This is on my USB modem. Now lets talk about the second device - my mobile phone. Trying to connect on *123# *111# and *135# all I get is "Connection problem or invalid MMI code". All I have left to say is *** With the complaint of bad service with regards to my phone screen replacement - I got 2 apologies (thank you very nice of you) and still no idea where my phone is in the system and it is now 11 days after it has been handed in.
