Poor customer care and phone lines

The only reason there is one star is because I could not write this without selecting one. I have never come across such a company ever. You try and call this company to resolve or clarify a issue, but there is no answer or you call numerous times and lines are crossed where there are 3 clients on an answered line. Quick to call you for money, but very poor with getting hold of someone that can actually help you with a query. I am so frustrated and disappointed.
