[Resolved]  Matrix Cellular — Overcharged bill

Address:

Khordha, Odisha

I am from India and recently went to Singapore for a four day trip. My plan was to take a local Singtel prepaid connection on arrival at Singapore airport.
However, at international departure terminal at Kolkatta airport, the salesmen of Matrix cellular convinced me to take TWO Singtel simcard saying it is cheaper than taking a local SIM in Singapore. He assured us saying the same Singtel card which you will take on Singapore arrival will be given to you here pre-activated without any difference in Tarrif. He did not even bother to disclose that they have given me a postpaid card instead of prepaid.
In a hurry, we took the connection. He asked us to sign a form and took Rs5000 as security deposit and assured balance amount refund after we return back.
However, post return to India, we called the matrix guy and handed him the SIM card at kolkata Airport. The matrix guy said, you will get the refund after bill is generated. But on the contrary after one month I was emailed the telephone bill of matrix, claiming Rs 18000 for both the Sim cards.
The Difference in TARIFF in Singtel Card given by Matrix compared of Singtel Prepaid Card at Singapore is as follows:
1. Matrix charges a fixed rental SGD 1 = Rs 37/- PER DAY. Singtel charges a one time sim card charges of SGD 10 with validity for 90 days. Singtel deducts SGD 0.60 per day for free incoming.
2. Matrix local call charges at Singapore = Rs 11/- . Singtel varies from Rs 3/- to Rs 6/- depending upon peak or unpeak hour usage.
3. Matrix ISD call rate from Singapore to India is Rs 33/- per min whereas Singtel call rate with 019 dialing is Rs 6/- or less.
In addtion Matrix charges are costlier as mentioned below:
1. They charge airport fee of Rs 150/- per sim if bought at airport
2. They are charging a surcharge of @10% of bill amount.
The above charges were not informed to us at the purchase point and they take signature from you in a hurried manner in a paper where these charges are mentioned. They just take security of Rs 5000 and assure refund immediately on returning back.
Singtel Prepaid from Singapore would have billed me Rs 1000 for both the cards while Singtel card given by Matrix have raised a bill of Rs 22000 just for a 4 days trip to Singapore.
