Unhappy Customer

I had a very bad service with them not wanting to take ownership and accept that it's their fault, my 3 accounts were blocked claiming I did not pay 2 debit orders went off 20th December 2019, asked for their team manager 3x nothing was resolved. Today they gave me time frame of 5hours after that I called they advised me payments is closed must give them 24 hours to open the 2 Sim cards. I'm so angry and unhappy about this service.
