[Resolved]  Club Mahindra Holidays — Asking to pay gst difference amount after taking membership

My membership I'd is 2632379,
I have taken the membership in 2015 and completed the payments of emi in 2019, i have agreed to.pay the membership fee in terms of emi and all the tax present at the time of taking membership is also agreed to pay as emis but when the gst increases how can you ask the customer to pay the gst difference when we have already taken the memebrship, if it's some new membership then u can ask a customer but for members who have already taken the membership you are not authorised to collect the amount stating gst difference. Do u take car loan and when ur paying emis if suddenly gov increases tax do you pay extra tax àgain no right then same applies here when u sell the memebrship u clearly state that irrespective of price hikes ur membership amount will not vary and the commited amount which was quoted at the time of selling membership will remain same even i[censored] pay in emi then suddenly how can u come and charge gst difference it's simply looting the customer such stupid tactics ur playing on the customer we should file a complaint against you in consumer court
