Bad Service

I previously had an account with Mobicred. Then their service was great and had no issues. I tried to reopen the account and they said it wouldn't be a problem. I have called numerous times. Either they don't answer their phone or when they do answer (the 4 or 5 times they eventually answered) I got told they don't know why it's taking so long and they will resend to the finance department and give me feedback soonest. My emails don't get answered at all. I find this service has reached level 0 in customer service and completely rude and ridiculous to treat customers this way. I am so angry that not one staff member has made any effort to return my emails or calls and this is so pathetic. How do they run a business like this ?
