JJ withheld important information from me.

On 3 March I upgraded to a new contract.JJ handled upgrade,he explained very little to me.Since I upgraded 2 months before the due date,he showed me on the computer that for the next 2 months I would still be on my old contract and paying for BIS.Thinking that I still had BIS for 2 mnths,on 7th I downloaded ringtones from Zedge< free site.Ended up with NO airtime!Anxious I phoned Cstmr Care(REF:S3-8Z72D-D8MTZ) and found out that the phone does not SUPPORT bis!I new when the new contract kicked in I would start using data bundles but he never told me the phone doesnt support BIS!Store manager(Sinki) was unhelpful, never phoned me back,I had to go see him.He said that JJ denies everything and says that JJ said he activated data bundles for me.Sinkie checked that and when I phoned HIM after 3 days,told me JJ had NEVER activated the Bundles.When I asked him how he was going to resolve this and compensate me,he insulted me and told me he doesnt know if me or JJ is lying- that after JJ **** to his face.Pls check my account,I work responsibly wth airtime.Widow, pension only income, pls help me I cant replace that R350 airtime that I lost. Sinki is protecting JJ, will Vodacom protect me??
