Greedy Retailer

I bought a lounge suite from morkels which is now using Bradlows both of which have poor service because when i bought the furniture I got it about 2 months after the period we agreed in terms of the contract, I had recourse to cancel the arrangement due to their breach but i didn't and when the furniture finally arrived I paid ahead and completed the payments 2 months before the time intended in terms of the contract and they owed me R236 which i went to the store and notified them of such they informed that i should escalate the complaint with their customer service which I did and they assured me the dispute had been escalated and resolved and my account reflected a 0 balance but beware and behold I got an sms on the 24/11/2017 after the account was settled in September 2017 stating that i now owe R249.14.

What is annoying is that they will probably debit this amount from my salary when i get paid and i cant reverse it because if i do it will reflect negatively against my credit profile. I am now tired of giving this store the benefit of the doubt because it is clear that they deal unfairly with consumers because they are aware that very little can be done to them because of their size but my experience with them show me that it is one that an individual needs to be very weary of when doing business with them. They breached the agreement twice and couldn't even live up to their supposed remedy, overall a very bad experience with a store that advertises itself as one that can be trusted but i now hold a completely different opinion.
