Tasmac — Threatening and using filthy language for 10 rs extra

On 19.04.2021 i went to the tasmac shop no. 4013 in chengalpet situated at: s.no: 144/2b thimmaraja kulam G.S.T.road, Chengalpet around 18.27. hoursto buy a rum bottle and asked the shop men and paid 125 rs. But the shop men threatn me to pay extra 5 rs and throw the amount which was paid by me, then i asked the person the M.R.P rate was 120 rs, and i have paid 125 rs with extra 5rs and your asking extra 5 rs again in a threatening manner is against law in a polite manner, but the shop men started shouting in a filthy language and in un parlimentary words. immediately i told i will compliant to the tasmac officer if he does not stop using the filthy words, but the shop men again uses the filthy language and un parlimentary against the officer and also told that the officer only instruct them to get extra money from the public so that if i compliant also nothing will happen and again started shouting in filthy language. Thia is happening in all tasmac shops . Pl kindly take departmental action against the person failing which i would be constrained to take legal action against you and the employee under the relevant laws making you and your employee to held liable for all costs.
