Rain made me pay twice on the same month

I had to pay twice for my internet this month... Payment bounced on the 1st because I had switched off online payments... I then did a manual payment on the same day, but the system had written that I am in arrears for 699, assumed it was a glitch so I paid, the following day on Sunday, my services were cut because apparently I didn't pay... I had to pay again because their support desk is so unreliable and since I work from home I need internet.

This was escalated on the same Sunday, 2nd of August and their consulant came back to me saying that they need the bank statements... Sent the back statements and the consultant came back to me saying that I need to speak with my bank because she can only see 1 payment.. How can i speak with my bank when the payments show that they went through to rain. I haven't received any feedback, today marks the 13th day with this is still pending.
