STAY AWAY FROM RCS PLANTINUM CREDIT

I have not had access to anything relating to my credit card with RCS, I don't receive statements, he app has not been working for months, they refuse to lower my limit as I pay my card, I will be escalating RCS platinum creditt card to the relevant ombudsman i have been complaining and reporting amd every time they say "your request will be escalated" and them nothing, for all i know they arr not allocating my payments o4 lowering my outstanding balance, because i have NO access to the account unless i use airtime and phone, just to be held online for 20 minutes or longer,
