Double Charging Rain

I recently changed my payment date from the 25th of May to the 1st of June. On the 28th of May, I then made payment. Surprisingly, Rain disconnected my Internet connection on the 2nd of June still wanted me to pay the same amount I had just paid. I tried to contact the service provider by his phone was muted therefore I couldn't hear anything that he said. I am kindly requesting that they check their system to see if payment has been made already because I do not understand why I am being charged double the feeand why this was not communicated at the conception of the contract. It does not make sensefor me to pay for a full month for less than a week. I would expect the charges to be pro rata instead. I would also like to request that my payment date be reverted back to the 25th and my that my connection is restored. It is really frustrating because all ofthis should have been communicated on the day I entered into an agreement with Rain. Does it mean that one is no longer allowed to change their dates to suit their financial position? If so why was this not communicated? Because now it means that I will have to be disconnected every month and have to pay a reconnection fee, which is not fair. Why do you put the option to change dates and then not explain it in full. This sounds like daylight ******* to me.

Kind regards
