Double payment made but according to Gosolr I am in arrears

Today I received email from Nible Credit Solutions reminding me that my account is in arrears and that my GoSolr system is at risk of being de-installed due to non-payment. What nonsense. On the 29th of January I made a manual payment and on 1 February a debit order was taken from my account. I called 3 times to sort this out to tell them not to raise a debit for the end of Feb. Sorry our finance department dont have lines, I will escalate to them to call you back. I am still waiting until now. Now I am getting a snotty letter from a creditor regarding an outstanding account. I called now again and held on for over a half an hour to speak to no one. Gosolr really is this how you treat your customers, when your finance department cant allocate payments or phone clients back. Seriously shocking service
