Poor service

I cannot receive sms or notifications from institutions and banks etc... I went to my 2 banks they said everything is fine from their side Vodacom walk in centers checked and they advise me to call the relevant department or customer care i phone them and they phone me back I explain that i cannot receive sms's only from person to person that's all . They lady said they going to escalate it but up until now its a no show i am disappointed :(
