Afrihost cannot allocate my payment for two weeks and refuses to reinstate my account

My account was disabled due to non-payment when my business had severe cash flow issues. I have paid them in full on 26 May 2020 with immediate payment. Today is 8 June 2020 and they have still not reinstated my account. I email the daily and they just reply saying that my payment has not been cleared on their side. I cannot invoice my clients etc so in these dire circumstances their incompetence would potentially mean that I would have to close my business. You cannot call their account department as it takes 2 hours for them to answer. It is a mess and I am not sure what to do.
