Double billing!!!! Do not signup with Home Connect!!

Seems like I just can’t get the service from HC as a new client to be impressed or happy signing up with them! I paid the prorated amount when the activation was done earlier this month, I’ve sent through the proof of payment YET this morning to my utter dismay I’ve been double charged!! The prorated rate and my subscription for August! What is wrong with this company that they can’t get it right?? Is it the calibre of people they employ?? How many hours do I have to spend sorting out their lack of engagement and customer service?? I have no words and I can honestly say that I will not recommend HC with a clear conscious!! The worst service ever!
