pathetic service

i have a telkom mobile contract which the unlimited telkom to telkom mobile has expired. i received notification on the 29/12/2014 that it has expired. 2/1/2015 we visited the telkom offices at midlands mall to add on the R49.00 d/o for the unlimited option. a call was made to the centre and we were assured that all is well.5/01/2015 i called the call centre to confirm. i was assured it was done. today i make a call to the nominated telkom mobile and the call was cut with limit reached. i thought 'how can this be'so i call the call centre only to be told that i have to do this R49 option every month . there is no d/o option. i was not told this . i was told to call later as there is high call volume . where is the service???then the call centre consultant then says that i cannot get acc. info cause acc. does belong to me. been to the midlands mall branch 3 x to sort this issue out as my dad is an existing account holder, we thought it best to do the contract on his as it makes no difference since i pay for it. so how many times must 1 do things for a company to get it right and what about providing correct information. staff don't know their products & features!
