Fed-up with low coverage and network problems

What the heck is going on with Cell C? I really can't be expected to pay nearly 1600 a month for data and calls and not be able to use it.For the past two weeks the coverage has gone down considerably. When you complain then only do they listen and then problem is fixed but it doesn't last for 24 hours then you back at not being able to access the internet or even opening your apps.Every month Im sitting with exactly the same problem. End July can not come quick enough for me to switch to a different service provider.
