Shocking Service

I have been attempting to settle my CTM account with RCS since last year. Their contact centre should be closed down as they offer no proper assistance. Every time I make a payment thinking I have settled my account finally, I get a call saying I owe them more. Even after emailing proof of payment they are unable to reconcile their accounts. They promise that your request will be honored and someone will return you call to ensure your query is dealt with but no one calls with a resolution. Instead you get a call asking for payment on another outstanding balance that you assumed you already settled. I called the contact centre so many times requesting assistance with no joy. Even their team leaders are useless. I am utterly fed up. I will never do business with RCS ever again. Don't call people and offer them credit when you cannot keep your existing clients happy. Putrid disgusting service RCS!
