POOR SERVICE

Bad service from dstv i have requested a refund for an amount i paid in error last week Tuesday i spoke to Shannel and Slindile who requested that i send my bank statement and copy of my ID (failing to tell me that i must put my customer number on the subject line of the email) to *** which i did, seven working days has lapsed and today i am told that i did not put the customer number on subject, today i have sent numerous emails with the same documents and contacted the call center and spoke to Fezeka, Sibahle and Ayanda on which even now i have not been assisted and i dont even know if my query has been logged or not.
