LTE speed slow after renewing contract

I truly believe Telkom is abusing their clients on contract.

My telkom LTE contract expired earlier this year, and because my signal was very poor (they told me I was in an area with a poor signal) I did not renew the contract. rather letting it continue month for month until we could get fibre. When the contract expired, suddenly my speed was wonderful, and I got around 30 to 40 Mbps. awesome right? I thought maybe telkom upgraded in my area due to the fact that Fibre was being installed, and as they had a new LTE deal for 100 gig at a special price, I thought why not renew and upgrade my contract? Makes sense right? WRONG!

a few days after we have upgraded the speed fell once again to below 10 Mbps. As I am working from home and need the speed this is really frustrating!

It cannot be the router, as we still had great speed the first few days with the new router, so my only conclusion is that they realized I was back on a contract and throttled me.

My question is why? should clients on contract not get BETTER service and speed? So if they cannot sort this out, I am definitely going to cancel this contract, as it is delivering what it promised to deliver and I cannot use it for my intended purpose.

I logged a call and they said a technician will come out, I am sure the guy is going to tell me that it is the area I am in, just like last time...

With telkom, it seems that you should rather stay on a month to month!
