Using *********** service providers to harrass us!

Received one call around 7am. Before I could reach it, it disconnected. Mr Delivery, your service provider are disgusting. Immediately after this, I received several SMS's to say they couldn't get me and I must contact them. I immediately phoned them only to find that they are not open until 8am. Then which idiot is delivering at 7am when they only open at 8am? Worse was the harassment. Don't they get paid for their job? Couldn't they phone me back when they opened? No, they chose to harrass me with SMS's, one after the other to say I must contact them and when I did, they don't answer because they are not open!!! Please you disgusting people, do your job properly. FNB how can you be so uncaring about your clients? How can you punish us with such *********** fools? How can you pay or make us pay for a \service"that is non-existent? This is complete arrogance on your part"
