Incredible Conection taking online payments then ignore providing the goods.

On 28 November 2019 I made an online purchase Today is 6 Dec 2019 and still no sign or communication regarding my delivery.

Tried the call Centre but no luck. Tried FB but the person responding says I will be contacted before delivering or I must contact the call centre

What must I do now????!!!!!!! It feels like theft as my payment went through but now Incredible Connection is suddenly mute about anything

I will take this further legally if it is not resolved
