VODACOM NETWORK CONSTANT ISSUES

Being a Vodacom user for over 10 years I have to say vodacom has become one of the worst networks in terms of providing services... for the past 2 months network has been constantly down and I'm not even over exaggerating to say it's down more than 70% of the time! This has become highly frustrating as I drive daily and rely on Google maps which I cannot use... I generally stream music which I cannot do... its month end and I cannot use my banking app because the network is constantly down for hours and sometimes days! Call centre blames the area however others in the same household will have network fine and mine will be down or vice versa... are you guys now throttling users because you can't keep up with demand? Every few minutes the network will come up slighly to like 3mbs speed for about 5 seconds only good enough for your messages to come through and that's it... Furthermore we are tied down to 2 and 3 year contracts which we must pay and we are charged hefty fees if we want to terminate early? Why make us pay monthly when you clearly cannot provide the service ????? Totally unacceptable..... Side Note: I've been trying to post this for the past 3 days however only just managed to do it now...simply because...my network is never working !
