Airtel — airtel xstream fiber id[protected]_mh : getting charged for fixed phone line though i asked for only broadband connection at home

Address: A603 AVON MAJESTY, DATTAPADA ROAD BORIVALI EAST, OPP TATA SSL, Mumbai City, Maharashtra, 400066

This has reference to broadband connection on 9th jan 2020 for my residence and paid for full year.
1. Airtel representative also installed fixed landline as it was bundled and free of charge
2. Told the person that i do need the fixed line as already have 2 mobile connection and no need for additional fixed line
3. Started getting sms and mails to pay rs352.82 for fixed line even though i have not opted for it and now being threatened with late fee if not paid by due date.

This is unethical way of doing business and left bad taste on switching to airtel service.

Another issue is, none of the sms or email provides the account details thus unable to even speak to anyone in customer support as it's required to key in account details.

Tried calling the representatives who had visited to collect payment and install the line but even they are not ready to share the account details which is very unprofessional way of treating customer.

This is the first time i opted for airtel service and have extremely bad experience with weeks
