Paying for a contract and getting no joy

I took out a contract with Vodashop The Glen on the 14th of May and 2 days later i had to return the phone as an OBF andLucus confirmed that it was not functioning.It was sent in for analysis,i was told by Lucus if i wanted when the phone returned i could take a different phone on the same contract as i expressed that i don't want to constantly have problems with a phone needing repairs.I only received 1 phone call concerning the progress of the phone and thereafter any info about it, I had to Call to check.Its been over 3 weeks and I have no solution and no phone BUT Im debited for it. I went in last week and was told the phone is not there and I will be called by Tuesday - No Call!!! I Called on Friday spoke to Lucus and then was told the head technician will call before business hours ended but again NO CALL!!! When I called today and Daniel told me that the analysis came back as no problem with the handset. NO CALL FROM THE STORE AT ALL with any feedback -I HAD TO CALL - i was also told nothing could be done as the Lucus wasn't in,and will not be in till Monday. No Apology was given for not contacting me norany interest expressed in getting a solution - Extremely unsatisfieD
