Very poor service delivery

Once again I have to write to complain about pathetic service delivery from Virgin Mobile. They agreed to do a upgrade if I pay the Handset Buyout amount. After I have done this and emailed proof of payment the people responsible are conveniently not at work to do the follow up. I have been with Virgin Mobile over 6 years,have 6 contracts with them and spend up to R3500 per month with this service provider and yet when we request something you have to lick someones **** to get something done.It is down right pathetic and very **** service from this company.All I asked for is an early upgrade on an account which is due in July 2015,paid the outstanding handset buyout and now when I phone in everybody just doesnt do anything to help.They stuff us around and dont care their attitudes are *** and I will not leave this here. I wil be writing to Carte Blanche and all the news papers to show them what type of service provider we are dealing with. I am sick and tired of supporting such pathetic companies and they get away with it all the time.
