PLEASE NOT AGAIN!

In January 2016 my account was sorted out (by Shobha, thanks to her) which left me with a credit balance. To-day I received my 1st account after the credit and lo and behold it is wrong. The monthly charges on my account, for years, has been Telkom line R149.75, DSL Fast Bundle R130.73, Closer Callcatcher R7.80 and Telkom Evening W/Ender Plan R5.66 = Total R293.94. This months account reads Telkom Simple, DSL Fast Bundle R144.74, Telkom Evening Plan R180.76 and Softcap (10 gb) R86.84 = Total R412.28. Why have my charges changed. Also on your Mobile department - On Tuesday the 8th March I took out a contract at your Hemmingways shop for the special of a samsung phone and tablet. I have the tablet but the phones were out of stock. I went back again this past Tuesday and still no stock of the sumsung phone. Please tell me when can I expect my cell phone. I have signed for everything, am I going to be billed for this contract before I get my cellphone??
