Poor, bad service

I opened a cheque acc, 1stly grand central branch sent me all around to collect card, finally getting from other branch St Georges mall, after waiting in line for almost hour, consultant don't take all required docs, creates another profile instead of linking it, now 2.5 weeks later, still unresolved, visit branch 5 different times, spent over 3 hours in bank, still not resolved and to think it's a platinum card, I'm almost at an end for words with the poor service I received.
