Lazy Sales Rep at Home

Called in to Telkom at 17:43 to apply for LTE and Smartvoice deals. The sales agent then told me her system is offline and to call back in 5mins, I knew she was lying and that it would be afterhours and wont be able to get through because her tone of voice changed and she was at home. I then decided to not drop the call to enable me to rate the call, she then also refused to hang up and the said "I am terminating this call, client not responding" x3 and then dropped the call. I take it this is a tactic used by Telkom employees to avoid being caught not doing their job properly. I suggest management check these calls close to closing of business. I get the feeling this is a tactic being used on a daily basis.
