Frustrated

First upgraded a contract which did not suit my criteria as requested. Waited 3 months to cancel or upgrade out of frustration. After 3 months was sold something that would work for me. On the second day noted all data and airtime was 0. On query noted the wrong contract was loaded on the system. After numerous calls utilizing 135 Number and being transferred from one department after much frustration was given a ref no in that it would be fixed in 48 Hours. Text was received 4 hours + later and behold wrong package details were loaded. Try follow up on the reference and wish you all the best. Don't know if it can be fixed after many mistakes
