Vodafone India — unusual access fee by vodafone india

Address:

603203

I have done a recharge rs 45 via paytm for mobile no. [protected].
In return i got this msg from vodafone: "rchrg of mrp rs 45 on 26/03/18 successful. Tlktime rcvd rs 2.74, gst rs 6.86, access fee rs 35.40, new bal rs 0.01. Transid onr[protected]. Dial *111# for a/c info.."
Now can anyone please explain to me that even after deducting the gst of rs.6.86, why was the additional amount of rs.35.40 was deducted under the subtitle of "access fee".

Plz return my money and explain me on what basis vodafone deducted this??
Kindly look into this matter as soon as possible
