Over payment on my monthly bill

[JMoore]

Hello, I have called and been on hold for over an hour now!!!! Get intouch with me asap or I’ll cancel my direct debit! 
you have over charged me for the last 3 months and was promised I was going to get a credit in the next 2 days! Where is it and why are you so hard to contact!?
