Reliance Communications — Landline phone & plug and play

Hi, This is regarding the land line phone which I had issues and was resolved thru consumer forum. So taking the assuring from Reliance communication customer service I renewed / retained my land line connection. However again I face the same problem. I got a mail in my inbox informing that the no is over used and has crossed the credit limit. Im very much irritated with this service provider. Apart from that I also brought a plug and play wifi device for my home. The first free data is over only with the usage of whatsapp messages. The free data is not carried over to the next recharge. With minimal usage the data gets over and Im unable to use apps like Skype, hangout etc., I will stop using Reliance for my life time and also inform my friends not to go for Reliance connections. FYI, my land line reliance no is[protected] and my wifi data no is [protected].
