I was traveling to Philippines in the month of sept& I took Philippines SIM card from scam company matrix When I bought this they told me I will get 5GB OF DATA& 200mints of indian calling free.My internet didn't work at all I was on holidays I wrote E-mail while I was wifi in my hotel made call to customer service& mentioned issue becouse iwas getting network but not INTERNET they were not able to fix the issue and because of this my whole travel planed was not smooth& when I was talking to their customer service they told me I will not charged anything as my Internet didn't work.
So when I reached delhi they sent me bill of saying I made 6 calls and for that you have to pay 12k which I was told free st the time of taking connection 200mints was free. I spoke to their customer service they r saying they can give me discount of1700₹ and I have to pay remaining.
They gave me their senior email it's useless I wrote email to them no reply now receiving calls from their collection guys threatening me to pay the bill.
It's better use your own ph no while roaming that will be cheaper then taking matrix SIM card and with matrix you can rely and you can't expect any professionalism .stay away from buying MATRIX SIM CARD because ot will not work during your travel& once you back you will be more frustrated with their calls and unexpected billing.
