Credit limit has increased

I received my monthly statement confirming account transactions as well confirming (That is why you have been selected to receive a credit limit increase -<br> it's our way of saying thank you for effectively handling your account.)<br> <br> I tried making a purchase and was told not enough funds after been sent the statement confirming: Your credit limit has increased to R6,939.<br> This means that, from 12 November 2015, you can spend R2,035.22 on your<br> Markham card, giving you the chance to shop and shop some more. <br> <br> Signed of by:<br> Eugene Maree<br> Customer Services Manager<br> <br> I called the customer care department advising them the problem and was told it was in error no communication been sent out advising me this as I was made a fool in store.<br> <br> To top it off they will send me a R200 gift voucher to say sorry as they done it for all other customers.<br> I'm not all your other customers.<br> <br> So I suggest I get feedback or I can take the matter further.<br> <br> Thank you.
