Matrix Cellular International Services Pvt Ltd — unwarranted data services charges on dubai sim

Address:

West Delhi, Delhi

i opted to use two sim cards for dubai and was told of plan by their executive mr. C that the lowest plan is something rs. 600 and there would be free calling between the dubai no. upto certain limit and free incoming .
However to my surprise they have charged me for the data services not used by me at all on bote sims amounting to about rs. 8500 plus and on asking them to revert the charges the reply is same that the GPRS is preactivated on dubai sim and the on smartphones it gets automatically activated
so they mean to say that you use a silly old phone and not a SMART PHONE where as most of the phones are smartphones and then all samsung ,lg, and apple users would have to bear such a charge . so be aware of matrix and do not listen to their advice and do not get into agreement for billing them through the credit card as you would be charged any way and there is then no way to retrieve the overcharged money.
i have written the complaint but there customer care says that this what you agreed through the agreement but forgets to say that theydid not inform or fully make me aware of he same and that also amounts to breach of faith .
I hope that some sense prevails in their mind to maintain good customer relation
