HP attorneys ****

Keeps on calling me about 10 times a day in regards of a phone contract I took out for someone else. The contract currently can't be paid as both me and the person with the contract are unemployed. We made so many arrangements with cell c and the so called lawyer firm who doesn't even have a office. But still they keep on harassing me, they are no professional at all for a so called Laywer Firm. Now they are trying to get my banking details and all my personal information to deduct money but how will they deduct anyways if I don't have money ? They should just stop this is already 10 months they been calling me non stop.
