Dropped calls

Too many dropped calls and you tell me I can get get it back between the hours of 12 and 5am when we are sleeping why? what’s the point and when I check my invoice it’s not even credited to my account. So that’s a lie and *****ing ?? And only Vodacom to Vodacom you not the only net work I call !! Can you give me an answer and a refund as you have promised !!
