I took a sim card for my travel to USA in October last year. I was supposed to fly with Etihad which goes via Abu Dhabi. The Matrix employ send me 3 sim cards. One for USA and two for UAE-going and return. I asked him why? and he said, just for your comfort during layover time and there is no extra or hidden charges. My USA sim card came with 1000 minute free talk time to India. I paid approx. 4000 rupees cash for sim card service, which he said will be adjusted in the final bill.
When I returned to India on 1.11.2014, I send back all the three cards to Matrix. They sent me a bill of 5500 something, which I thought would be adjusted with the cash I paid in the beginning.
To the utmost shock and surprise to me, the Matrix people swiped my card and charged Rs. 5800/- (approx.) and then 1, 25, 000/- from my credit card, without my authorisation or even pre-information.
They told me that Rs. 1, 63, 000/- is payable for data usages charges on the UAE card, which was never asked by me and never used also. (I have a local sim card o[censored]AE, as I am a resident there).
It is shameful and a broad light robbery. Was this information helpful? |
