I HAVE BEEN WAITING FOR A REFUND FOR 3 WEEKS

I settled my RCS account on 24 April using the balance supp**** on the credit bureau, i emailed my proof of payment along with a copy of my ID and bankstatement to [Email Removed] i phoned the call centre on 30 April 2015 to confirm if the payment was receipted, i was informed that they no longer use the email address i must send it to [Email Removed] by this time i received my RCS statement and realised i over paid so i sent my bankstatement and ID copy along with my proof of payment to [Email Removed] then i phoned on Tuesday 5th May 2015 and was told my refund will take 7 days i should call back on 12 May, when i called i was told RCS did not receive my email request for refund, i told the woman i was told last week it was received, she looked again and found it she told me that the refund department is working on it and i will get my refund by 14 May i phoned in again on Thursday 14 May and was told that refunds are not processed on Thursdays only Wednesday, then put on hold for 30 minutes. this is unacceptable i want my refund paid to me i have accumulated telephone bills waiting for your callcentre this service is totally disgusting
