I am so so p##d of about telkom and Mondo

I once got a call from Mondo selling Wi-Fi router on line. I didn't want to take it because it was the first time I heard about Mondo. It's when the consultant told me it's for telkom she even said we under telkom. It's when I agreed to take 2 routers on contract. They delivered the 2 Wi-Fi routers but without Sim cards.. I called Mondo customer service informing them I received the Wi-Fi routers but there was no Sim cards. They I must go to the nearest telkom branch they will assist me. I went to telkom branch they said I must call Mondo to resolve the matter because the wi-fi router were supposed to come with Sim cards inside the box. I called mondo again, at Mondo they said they will investigate the matter. And in the meanwhile they're debating on my account. I waited a month nothing its happening. I called Mondo please cancel the contract and please come fetch your Wi-Fi routers and they send courier company to come collect the package. I thought I'll see a refund, instead they debited me. I called Mondo to find out why? They told me I must call telkom. I collect telkom and they said they must investigate the issue. And all this was from May till today the issue is not yet resolved and they still debiting my account. I really don't understand are they unprofessional or is how they enrich themselves because I really don't understand the sistem they using. Where do they load the data that are am being billed for because I did not receive the routers. Telkom are ****** and ***********. How can a case like this take more than 8 months. I called telkom regarding this matter several times but the problem still has not been resolved. I regret a lot to put my self to unprofessional and carelessness people of telkom. I'm tired about this I no longer know what to do because I must do debit reversal every month.
