Overcharging on monthly bill

<p>While reviewing my current phone bill i noticed that the bill for the month was more expensive than I would usually pay. Upon further inspection I have identified that I am being charged R248 for a promotional 1 Gig bundle that i should infact be paying R99 for! This is unacceptable, what makes this issue worse is I am currently out of the country on business and am not able to contact the call center to sort this issue out! I would appreciate it if a representative would contatct me to fix this issue as soon as possible.</p>
