Complete lack of service

I am trying to open an EXPLORER contract as per your advertised 2 year contract. <br> I have called the call centre atleast 6 times and completed online contact forms to try and find out what is happening. <br> During the original call I went through the entire process of giving all personal information including bank account details to open the account. EACH time I call for follow up, I get told there is no information on my account and that it will be escalated and I will be called back. This has not happened ONCE since early January! Today I was given the number of your DPP department, which, when I called it, did not exist. I am beyond frustrated and have no idea what route to take next. This service is abomnible!!! Surely it shouldn't be so difficult...
