Absolutely useless and unprofessional support channels

<p style="margin-top: 0px; margin-bottom: 13px; color: #666666; line-height: 22px; font-family: 'Source Sans Pro', Verdana, Geneva, sans-serif; background-color: #ffffff;">Once again, I have experienced an issue with ABSA, as it has been happening quite alot the past year or so. No SMS received after exchanging rewards for airtime. It has happen a few times. Then I request them to resend the SMS. Easy as pie, isn't it? anyway, logged the query by email on 3rd of May 2016. 5 days later, the issue is unresolved. Really? Is it that difficult? SO this morning I send another email to request a follow-up. Email bounces back telling me the recipient's mailbox is full. Come on ABSA, are you this useless??</p>
