MISSINTERPRETATION WHEN SELLING GOODS

We went into Telkom Menlyn on 14 sept 2014, we filled in all the forms, my husband sent his bank statements the Monday, we waited for Percival to get back to us for 2 months. He explained to me and my husband that if there is mtn roaming our Internet will work. We asked him plenty of times. So I started talking to Jeff the manager at that stage about why our 3 contracts is taking so long. Then our papers got lost, And we needed to go back to Telkom Menlyn again to fill out the forms in November. We eventually got our 3 contracts. The first thing we noticed is that our night cap internet does not work, we phoned telkom Menlyn and Jeff told us to get a new simcard, so I told him everything is new, why isn't the night cap working? Then he said he logged a call, but we haven't heard anything from him. No reference number nothing! Now when I took this query higher than menlyn, the people tells us that if there's no telkom tower the night cap won't work. That is not the contract we took out, neither are paying for! We feel that telkom Menlyn sold us a contracts without explaining how it really works. We also feel that we were placed under misjudgment!
