Multichoice poor service

I am on the premium package with xtra view and even though my account is paid up to date by debit order my decoders get switched off due to an “arrears payment” message. Guests use my xtra view and I find this quite frustrating and embarrassing. I unlock the decoders via the Mydstv app but then damage is done and frustration huge. Multichoice struggle with their finances and losing customers at an alarming rate but their customer service stinks.
