No customer service what so ever

My package was upgraded to a higher speed at a fraction of the price that I was on and have been paying for a while. When it eventually got upgraded just after mid January I received a pro rata invoice at the new rate from the date of accepting the new package until the 31st of January. However I have been waiting for a credit note as my Supersonic debit order on the 2nd of January went off for the full month of January. Seems to me Supersonic only knows how to process invoices not credit notes. Now to make matters even worse get told yesterday I`m not on debit order it shows on my account that I pay via EFT. This is after I have sent my January bank statement to I don`t know how many people to show the debit order that went off on the 2nd.

There is NO customer service whatsoever at this Company..
