TOO MANY UNNECESSARY CHARGES

My mother is a 82 year old pensioner who has had an account with TFG for many years (easily 40 years) and has always been a good customer. However being a pensioner, she pays her account every month when she receives her pension. On numerous occasions she has informed the telesales persons calling her that she pays her account when she receives her pension. However, each time she settles her account, she receives her account stating that she stills owes money. Currently it is R69.28. This is not the 1st time this is happening. Furthermore, she receives phone calls, sms and letters (which is all being charged to her account). Why is it necessary to send her communication via 3 mediums when a call or sms is sufficient (one or the other, not both as she is being charged for everything. Seems like the sms, phone calls and letters is a whole new stream of income, it's just ridiculous. Old people being exploited. Why not allow pensioners at least a grace period to pay their accounts (maybe by 7th of each month) before harassing them for the money. You have had loyal customers for many years, show your appreciation by accommodating them in their golden years. Thank you,
