Bad service

2 Days (during SA Log Down) I had to upgrade my Rain 4G wifi. Today as agreed to activate my upgraded wifi they suspended my current wifi and deducted the increased amount from my bank account I have made desperate attempts to contact them, without any success!! Since my initial subscription with rain I HAVE MOVED AND IF THEY WOULD LIKE TO DELIVER A SIM CARD FOR THE UPGRADE I WOULD HAVE TO PROVIDE THEM WITH MY NEW DELIVERY ADDRESS I have been sending emails, phoning them (I understand they work on sceleton staff) to try and and inform them, but they completely ignore me IT JUST AMAZED ME THAT THEIR SERVICE WAS SO PROMPT DURING THE SHUTDOWN AND THEY DEDUCTED THE INCREASED AMOUNT FROM MY ACCOUNT. I even tried to contact them on their website but they ignore me completely
