Bad service received

I have considered using Hello Peter after I have send numerous emails to RCS to assist me with my query.

I made a final payment to close my account and have send numerous email attached my proof of payment to payments@rcsgroup but I'm told they haven't received anything from me.

I have made many attempts to contact them but was kept on the line for hours, and send from pillar to post without any resolutions.

I please request RCS to contact me urgently as I want to close this matter once and for all and want nothing to do with them anymore.

How can a big company like RCS takes their own time to allocate a payment, I need this matter sorted as soon as possible and interest to be reversed. Failure to do so I will have to hand over the matter further.
