disgusting people

I have had an account with lewis since 2021 where i had first purchased a fridge which is done played and a tv which I'm now still paying, i was retrenched and took my documents in to store, before handing over my documents i requested to see the amount i owed to see how much the insurance will pay and minus it from what i owe, their insurance monarch started paying and sent me a message every month when they made payment, even the stores sent a sms thanking me for making payment. After a year of payment i was working again and then made arrangement to pay what was left which according to my calculation shouldn't be more than a 2k but to my surprise i still owe the sane amount as when before the insurance made payment, i spoke to stores, head office but met only with no response or simply we will call you back but nobody ever does. A lady from the stores even came to my home and requested i make a loan to pay my account, asking me don't i feel guilty watching on that tv. Is this the type of employees they employ? One of their drivers even disclosed my account information with a neighbor. Im sick of this harrasment and if they clearly not interested in sorting this out im going to have to find a different route of dealing with them because they just don't care.
