No customer service

On the 30 of October I made a payment on my Rcs account at Cape unionmart. Due to some technical issues it didn't go off, only on the 31st October it went off my account . I have phoned Rcs customers care numerous times explained to the consultants witch was sensless. Send emails to no reply. To current the issue has not been resolved. Was asked three times for the same information (proof of payment and account) to no resolution. I am still waiting on supervisors tomcall me back as to date. This tipe of service is unacceptable. Would really like a solution. As my issue has acordingly been escalated still no response.
