****ed 😡😡😡 customer very ****ed off

I'm so fed-up with cellc. Took a phone on contract in 2019, my contract ended in 2021. I asked for a settlement letter and paid but to my dismay I still owe R2600. Apparently I had 2 accounts. I have queried this with their current attorneys without any joy. How can a Huawei smart 2019 cost almost R10 000. I'm so ****ed off and tired of being harassed by their agents. Cellc owes me money when I ask them to settle this balance which I don't know where it comes from they tell me they can't do that BCS it's a different account. Their legal department is as useless BCS I have made numerous attempts to communicate with them they give you their email address and don't respond to your emails. I'm ****ed to the core. They are ****ming customers.
