Bad service

Good day I have a contract for a portable router with Cell C, over the weekend the router stopped connecting and was just saying connected without internet, I went on the app on my phone on Monday and sent a message that it says connected without internet, got called today by some lady. The lady told me that should would transfer me to another department, the guy also could'nt help me apparently I was transferred to the wrong department, he said he is transferring me to the contracts department and somehow cut the call. I want it to be known by Cell C that this is not the first time this is happening and I do not like it, I do not give any problems when the debit order has to go through, yet I should just accept such mediocre service??? If this issue is not sorted out by Friday 15th July 2022, the debit order on the 25th July 2022 will be reversed and they can cancel my contract. I would rather get another portable router elsewhere.
