Irretating

On the 30 November I called in to migrate 2 of my numbers to prepaid as I had taken out 2 complete new contracts. I was told I have to call retentions as this cannot be done in store, after waiting 58 minutes on a call, I log the migration and I am told it would take 24 to 48 hours. On the 12, my contract is still in use and I get new data and airtime. I call again, wait another hour and they tell me it hasn't been logged, they are doing it now. Eventually a week later I call AGAIN. THEY TELL ME RETENTIONS ARE BACKED UP SO THEY CAN'T TELK ME WHEN IT WOULD BE MIGRATEDBTO PRE PAID. WHICH MEANS I AM NOW PAYING 4 CONTRACTS BECAUSE THEY ARE BACKED UP. RUBISH. ***
