Refuse to change my account to 6 months

In December 2014 we went to Edgars Paarl mall to change our account from a 12 months to a 6 months account. At the time, they were unable to assist us, and told us to send an email to request the change. We went home and sent the email, on which we never got any reply!!!!! This is unacceptable to begin with.<br> <br> This weekend, we were back in the store and asked them to change the account again, as we never got any feedback from the email sent. We were told, that the account could not be change anymore and that they force us to have a 12 month account. The sales assistant phoned the call center and after 15 min, we were still waiting, without any answer. The service is shocking!!!<br> <br> Above the poor service from the call center, there was only Mens Jean sizes in 28/30 and 26!!!!The whole store is full of those sizes, now, clearly they don't sell, get proper men's jean sizes in your store! The store is huge, but there is no clothes for sale, here and there, there is an item. <br> <br> Please contact me with a solution in changing my account to a 6 months account, or close it immediately.
