Service failure - 20 to 30 calls and still no resolution!

I had written a Hellopeter complaint before and one of your escalation agents called me to resolve my query. Only for the same query to be closed with NO RESOLUTION!!!!!!!!!!!! I cannot understand how something so simple relating to my bill can take almost 2 months to resolve. Your sales agents are ***** and sell products by quoting the wrong prices. Furthermore, your escalations channels are so poor that your Team Leaders and people who respond to these escalation don't even take ownership.
