Tikona — Complaint for billing

My user is is [protected] and my previous tikona plan was of 6 mbps, i was not happy with the tikona network hence i decided to disconnect the wifi, after placing the request i got a call from one executive from senior desk he mentioned that as you are one of our privileged customer we will offer you 10 mbps speed at just 1979 and he sent me a mail also regarding the confirmation of this amount hence i paid 1979 on 7th march, on 7th april this # are again generating a bill according to the previous plan and informing me that i have to pay 52 rs balance as its outstanding, they are so stupid that they dont even know that their senior desk had offered me a discount and hence i paid 1979, till date thats on 5 jun 2020 its showing that my amount is outstanding which is not the actual fact, hence i will not be continuing with tikona as their services are pathetic, every second day there is network issue, so hence i want to disconnect the wifi
