Detoriating service

Imso disappointed at the service cellc give us as their customers these days . I once had a contract of which I paid up in November 2017 than in 2018 Jan I reflect as if I owe and amount but when theý closed the account they took my benefits away though I had to pay for them at a later stage . And they took months to resolve my query. Pass that I requested a paid up later they said they will send it after I get a call ok I wait I get a call after 3 days and they say I will get the msg while speaking she den droo s the call when I check my emails nothing . But I reflect on the itc as if I still owe them Orrin payingn1200 for an account which imm not .
