nothing gets done

Hi I am fed up with Lewis store Welkom, I have purchased a fridge that doesn't want to freeze so I reported it in January and the lady said she would phone me the following week to get it fixed cause it is still under insurance, well it has been 6 months and after numerous calls and I'm still waiting. she is very rude and do not know how to speak to customers at all ,she still has the edacity to say we are not going to make a seen but I must be happy to pay every month on time but do not get a service at all. her excuse was that she was off for a month , but is she the only one working there why not give it over to someone else to assist. And then on Saturday the 24th of June I asked for a settlement amount on my account so I can settle it ...I settled the account and send the proof of payment trough and yet to my utter Suprise they have debited my account again on the 29th of June but the lady at the branch ensured me that they have cancelled the debit so what now let me guess I'm going to wait 5 to 7 working days for them to reverse payment back into my account *********** people that do not know how to do their jobs.
