Telkom

On the 19th of May 2019 I purchased a cellphone at Telkom online via contract, it was on a Sunday, the following day I received a call from them to complete my application which went well. Three days later they delivered ONLY SIM card to me of which I obviously took with an assumption that maybe the phone will come later (NB: it was my 1st time I bought a phone via contract and hopefully last time after this experience). I waited with no luck until on the 30th of May when I decided to go to one of their branches at Marshalltown to enquire since communicating via their Twitter account and calls was of no assistance, when I got there one of their agents assisted me and gave me the cellphone, a bunch of Huawei P30 Pro gifts immediately. On the 6th of June they came and delivered another cellphone, not knowing the courier - service provider - customer relationship terms at that time I took the package with an intention of returning it immediately to their Marshalltown branch were I collected the 1st phone. I immediately went to the branch to return it, when I got there I was told to call 10213 so that they can come and take the other phone, I did that sametime and continuously so, every time I call they ask for my details so that they can call me back but they don't, another agent told me that she gonna submit my query and promised that their courier will send me details about when they going to come and collect the package but till today nothing has happend. I am worried that come the debit order day I might end being billed twice because of their incompetence, long storry cut short I need advise/help.
