mpesa offline

I asked someone for money to buy medication for my baby she was sick because I didn't have money so I asked this person to buy mpesa and SMS me the pin number and he did I put my voucher and I was waiting for confirmation SMS so I thought let me go to the pharmacy maybe the SMS will come through on my way as this was urgent.I arrived at the pharmacy still my balance is zero I called the customer Care they said theyare having tectechnical problems but they will fixed it I waited the whole day of Saturday still nothing I calledthem again Sunday no help at all I got my money Monday with no apology nothing.mpesa is useless its a lie that you can get access to your money when you need it I mean my child was sick I had to buy medication with that money I had to ask this person again to rather transfer another money to my capitec account what if he didn't have another money what was going to happen?I understand banks sometimes experience technical problems but not the whole 2day its 15 to 30 min then they will work again.you can check my profile I am a loyal mpesa customer but the service I got its BAD very BAD.ITS USELESS IM CUTTING THAT CARD IN PIECES ILL STICK TO WHAT I KNOW AND USEFUL
