Worse furniture ever

I have a new account with Lewis Store and I had the worst experience ever. My montly instalment is R541.55 was due on the 1st on November. I have a temp cash flow, I went to the store in Bellville Voortrekker Road (Branch 108 )and explained the situation. I has R200 ehich I paid and the cashier told meto wait for another lady to explain the reason for not paying the full instalment. A woman called Roxanne came through, I then explained to her I will pay the remaining balance by the 15th of the month. She then threatened to cancel the deal, and demanded that I pay the remaining the day after. She speak to the clients as if she is speaking to her children at home, she looks down at people and is a total bully. I left the store feeling very disgusted and full of regrets. I then spoke to one of the sales consultants who told me that every client complains about her rudeness and nothing is ever done about that. I feel that she needs to treat people with respect, the mere fact I went to explain my situation should tell her that Im not running away, and still made a short payment.

On 16/11/2017 I visited branch 171 which is also in Bellville to make a payment of the remaining instalment balance. I was attended to by a lady named Ntombizanele. I had R400 in cash with me. I gave her the cash and advise her I am paying R341.55 and she took my payment book to open up my account. Few minutes later she told me she was done with the payment and gave me only my book. I requested for the change, she then told me she has entered the full amount on the system. I then explained to her that it is not what I had requested her to do,she then told me that she did not hear me.When attending to a client confirmation should play as a vital role She advised me to go to Branch 108 for a refund, and advised I dont have to go on the exact same day, after I explained to her my lunch hour was over. The receipt she showed me reflected a credit balance of R58.45.

On 20/11/2017 I went to branch 108 to request for the refund where I was assisted by Michelle who told me they cannot refund me,again called Roxanne who also told me with attitude that I will not be getting any refund and that the money is on my account for December instalment. I was sent back and forth and I still did not get the refund. Both store refused to take ownership of the incident ,I known its a small amount but still she was suppose to take the amount I told her I am paying.
